2019-11-01[Darwin, machopic] Back out part of PR71767 fix.Iain Sandoe
We applied a conservative, but fairly large, hammer to fix PR71767. However, ideally, we want minimise the number of symbols visible to ld64 and to match the cases emitted by clang (since that's what ld64 is expecting). Now we've improved the handling of indirections, we can make the indirection symbols local when they are in the regular non-lazy symbol pointers section. We will continue to make any indirections in the data section visible (since right now we have no way to track if a given symbol follows a weak global). This change makes no difference to handling of labels for constants (to be revised in a future patch). There's a mechanical change to a number of tests (allowing 'l' or 'L' as the indirection symbol prefix). gcc/ 2019-11-01 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-10-13 Iain Sandoe <iain@sandoe.co.uk> * config/darwin.c (machopic_indirection_name): Rework the function to emit linker-visible symbols only for indirections in the data section.

2019-11-01[Darwin] The need for FDE symbols is dependent on linker used, not OS rev.Iain Sandoe
For very old toolchains, the compiler generated extra symbols that mark the start of each FDE. We no longer need this (since xcode 3 era) - so, for compatibility with newer linkers, omit this when it is not required. Since we have detection of the linker version, we can use that directly to determine if support is needed. gcc/ 2019-11-01 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-06-18 Iain Sandoe <iain@sandoe.co.uk> * config/darwin.c (darwin_emit_unwind_label): New default to false.

2019-11-01[Darwin] The need for picsym stubs is dependent on linker used, not OS rev.Iain Sandoe
272356 For very old toolchains, the compiler generated pic symbol stubs that provide the necessary indirections. We no longer need this (since xcode 3 era) and it's more efficient for the linker to make one stub when it knows a symbol is needed that for us to emit them speculatively in every object. Our current codegen is making the assumption that a specific OS version uses a specific linker version - and therefore the presence of support could be based on the target OS rev. Of course, that's way too simplistic (most likely bogus for cross-toolchains) and we want to make things explict. Since we have detection of the linker version, we can use that directly (A config test for support for stub-less linking might also be feasible but much more involved). Finally, should the user wish to generate code that caters for export to use in an environment with an older toolchain, the generation of stubs can be forced from the command line. In addition to the points above, branch islanding and a long branch opt for PowerPC Darwin has become conflated with the emission of these stubs. 274379 There is no need to distinguish PIC/non-PIC symbol stubs. So we can use a single flag for both. gcc/ 2019-11-01 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-08-13 Iain Sandoe <iain@sandoe.co.uk> * config/darwin.c (machopic_indirect_call_target): Rename symbol stub flag.

2019-10-29[Darwin, PPC] Fix PR 65342.Iain Sandoe
The current Darwin load/store lo_sum patterns have neither predicate nor constraint. This means that most parts of the backend, which rely on recog() to validate the rtx, can produce invalid combinations/selections. For 32bit cases this isn't a problem since we can load/store to unaligned addresses using D-mode insns. Conversely, for 64bit instructions that use DS mode, this can manifest as assemble errors (for an assembler that checks the LO14 relocations), or as crashes caused by wrong offsets (or worse, wrong content for the two LSBs). What we want to check for Y on Darwin is: - that the alignment of the Symbols' target is sufficient for DS mode - that the offset is suitable for DS mode. (while looking through the Mach-O PIC unspecs). So, the patch removes the Darwin-specific lo_sum patterns (we begin using the movdi_internal64 patterns). We also we need to extend the handling of the mem_operand_gpr constraint to allow looking through Mach-O PIC UNSPECs in the lo_sum cases. 2019-10-29 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-10-17 Iain Sandoe <iain@sandoe.co.uk> PR target/65342 * config/rs6000/darwin.md (movdi_low, movsi_low_st): Delete.

2019-10-29[Darwin, machopic] Fix for 67183Iain Sandoe
When we're using the LLVM-based assembler (the default on modern Darwin) the ordering of stubs and non-lazy symbol pointers is important. Interleaving the output (current GCC behaviour) leads to crashes which prevents us from building code with symbol stubs. To resolve this, we order the output of stubs and symbol indirections: 1. Any indirections in the data section 2. Symbol stubs. 3. Non-lazy symbol pointers. At present, we still emit LTO sections after these. 2019-10-29 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-10-12 Iain Sandoe <iain@sandoe.co.uk> PR target/67183 * config/darwin.c (machopic_indirection): New field to flag non-lazy-symbol-pointers in the data section.

2019-10-29[Darwin, machopic] Preparatory patches.Iain Sandoe
This is a combined set of 5 patches that allows us to fix PRs 65342 and 67183. 276924 Make machopic_finish() static. 276767 Set a SYMBOL flag for indirections. We are able to treat these specially where needed in legitimate address tests (specifically, they are guaranteed to be pointer-aligned). 276708 Compute and cache indirection rules. This caches a check for the requirement to indirect a symbol in the Darwin ABI, and uses it where needed. We also ensure that we place the indirection pointers into the non-lazy symbol pointers section. Other placements have occurred with various platform toolchains - but these seem to have been unintentional so we match current platform toolchains. 276675 Consider visibility in indirections. For weak, hidden vars the indirection should just be as normal, that is that the indirections for such symbols should appear in the non-lazy symbol pointers table, not in the .data section. 276674 Initial tidy of Mach-O symbol handling. We want to improve the detection and caching of symbol-properties so that (a) we can make the compiler's output match the platform norms (b) we can improve efficiency by checking flags instead of inspecting strings. (c) The fix for PR71767 was a largish hammer and we want to reduce the number of symbols that are made linker- visible. This first patch is largely typographical changes with no functional difference intended: - Tries to ensure that there's no overlap between the symbols used in the Mach-O case and those declared in the i386 or rs6000 port trees. - Some improvement to comments. - Makes the naming of the symbol flags consistent with other uses. - Provides a predicate macro for each use. 2019-10-29 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-10-12 Iain Sandoe <iain@sandoe.co.uk> * config/darwin-protos.h (machopic_finish): Delete. * config/darwin.c (machopic_finish): Make static.

2019-10-29[Darwin, testsuite] Skip pr72802.c.Iain Sandoe
As fallout from 19315, which is not fixed on this branch, the presence of an unused static variable causes a 'promotion' of that to extern. This produces wrong code on Darwin when Mach-O PIC is in use (m32 X86 and all PPC). So skip this unconditionally, as noted in the PR trail, the usefulness of the test is questionable anyway. gcc/testsuite/ 2019-10-29 Iain Sandoe <iain@sandoe.co.uk> * gcc.c-torture/compile/pr72802.c: Skip for Darwin.

2019-10-29[Darwin] Amend section for constants with relocations.Iain Sandoe
Darwin's linker doesn't like text section relocations (they require special enabling). The Fortran FE, at least, seems to generate cases where the initialiser for a pointer constant can need a relocation. We can handle this by special-casing SECCAT_RODATA when the relocation is present by placing the constant in the .const_data section. 2019-10-29 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-10-05 Iain Sandoe <iain@sandoe.co.uk> PR target/59888 * config/darwin.c (darwin_rodata_section): Add relocation flag, choose const_data section for constants with relocations.

2019-10-29[Darwin] Pick up SDKROOT as the sysroot fallback.Iain Sandoe
For compatibility with xcrun and the behaviour of the clang driver, make use of the setting of the SDKROOT environment variable when it is available. This applies to both finding headers and libraries (i.e. it is also passed to ld64). Priority: 1. User's command-line specified --sysroot= or -isysroot. 2. The SDKROOT variable when set, and validated. 3. Any sysroot provided by --with-sysroot= configuration parameter. SDKROOT is checked thus: 1. Presence. 2. That it starts with / (i.e. 'absolute'). 3. That it is not / only (since that's the default). 4. That it is readable by the process executing the driver. This is pretty much the same rule set as used by the clang driver. NOTE: (3) might turn out to be overly restrictive in the case that we have configured with --with-sysroot= and then we want to run on a system with an installation of the headers/libraries in /. We can revisit this if that turns out to be an important use-case. So one can do: xcrun --sdk macosx /path/to/gcc .... and that provides the SDK path as the sysroot to GCC as expected. CAVEAT: An unfortunate effect of the fact that gcc (and g++) are executables in the Xcode installation, which are found ahead of any such named in the $PATH PATH=/path/to/gcc/install:$PATH xcrun --sdk macosx gcc .... does *not* work, instead that executes the clang from the xcode/commmand line tools installation.

2019-10-29[Darwin, specs] Fix driver handling of PIE options.Iain Sandoe
pie, no-pie and rdynamic are driver options, we can process them in the relevant place and drop them once dealt with. There's no need to generate a new header to process the no_compact_unwind which is applied on the basis of the target system. Support for the -pie, -no_pie and -no_compact_unwind options should ideally be checked at configure time, however the status quo is to assert that linkers capable of targeting the relevant systems support these options (i.e. we trust that the user doesn't attempt to configure inappropriately). TODO: check the availability of the linker opts in configure rather than trusting to the user. This will fix the fail of pie-7.c, which is a result of failing to handle the no-pie driver option. 2019-10-29 Iain Sandoe <iain@sandoe.co.uk> Backport from mainline 2019-07-03 Iain Sandoe <iain@sandoe.co.uk> * config/darwin.h (DRIVER_SELF_SPECS): Remove the linker cases.

2019-10-26[Darwin, PPC] Check for out of range asm values.Iain Sandoe
There are some cases in which the value for the max skip to a p2align directive can be negative. The older assembler (and GAS) just ignores these cases but newer tools produce an error. To preserve behaviour, we avoid emitting out of range values. 2019-10-26 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/darwin.h (ASM_OUTPUT_MAX_SKIP_ALIGN):Guard against out of range max skip or log values.

2019-10-25[arm][PR88167] Fix __builtin_return_address returns invalid addressRichard Earnshaw
This patch fixes a problem with the thumb1 prologue code where the link register could be unconditionally used as a scratch register even if the return value was still live at the end of the prologue. Additionally, the patch improves the code generated when we are not using many low call-saved registers to make use of any unused call clobbered registers to help with the saving of high registers that cannot be pushed directly (quite rare in normal code as the register allocator correctly prefers low registers). 2019-05-08 Mihail Ionescu <mihail.ionescu@arm.com> Richard Earnshaw <rearnsha@arm.com> gcc: PR target/88167 * config/arm/arm.c (thumb1_prologue_unused_call_clobbered_lo_regs): New function.
