2018-10-01Switch syscall(2)/__syscall(2) calls to libc calls on NetBSDKamil Rytarowski
Summary: When possible, switch syscall(2)/__syscall(2) calls to direct calls of internal libc symbols. Add a new function to detect address of a libc symbol of a function that could be intercepted. With the address detector in GetRealLibcAddress(), an optional interceptor of libc call will be bypassed. The original approach with syscall(2)/__syscall(2) wasn't portable across supported ABIs and CPU architectures. The indirect syscall interface is also a candidate for removal in future revisions of NetBSD, as the C language ABI is not a good domain for serialization of arbitrary functions arguments. Switch the following functions to libc calls: - internal_mmap() - internal_munmap() - internal_mprotect() - internal_close() - internal_open() - internal_read() - internal_write() - internal_ftruncate() - internal_stat() - internal_lstat() - internal_fstat() - internal_dup2() - internal_readlink() - internal_unlink() - internal_rename() - internal_sched_yield() - internal__exit() - internal_sleep() - internal_execve() - NanoTime() - internal_clock_gettime() - internal_waitpid() - internal_getpid() - internal_getppid() - internal_getdents() - internal_lseek() - internal_sigaltstack() - internal_fork() - internal_sigprocmask() - internal_sysctl() - internal_sigemptyset() - internal_sigfillset() - GetTid() - TgKill() This revision leaves room for refactoring in subsequent commits.

2018-10-01X86, AArch64, ARM: Do not attach debug location to spill/reload instructionsMatthias Braun
Spill/reload instructions are artificially generated by the compiler and have no relation to the original source code. So the best thing to do is not attach any debug location to them (instead of just taking the next debug location we find on following instructions).

2018-10-01[X86] Add more test shrinking with truncate and sign bit usage tests. NFCCraig Topper
2018-10-01Distinguish `__block` variables that are captured by escaping blocksAkira Hatanaka
from those that aren't. This patch changes the way __block variables that aren't captured by escaping blocks are handled: - Since non-escaping blocks on the stack never get copied to the heap (see https://reviews.llvm.org/D49303), Sema shouldn't error out when the type of a non-escaping __block variable doesn't have an accessible copy constructor. - IRGen doesn't have to use the specialized byref structure (see https://clang.llvm.org/docs/Block-ABI-Apple.html#id8) for a non-escaping __block variable anymore. Instead IRGen can emit the variable as a normal variable and copy the reference to the block literal. Byref copy/dispose helpers aren't needed either. This reapplies r341754, which was reverted in r341757 because it broke a couple of bots. r341754 was calling markEscapingByrefs after the call to PopFunctionScopeInfo, which caused the popped function scope to be cleared out when the following code was compiled, for example: $ cat test.m struct A { id data[10]; }; void foo() { __block A v; ^{ (void)v; }; } This commit calls markEscapingByrefs before calling PopFunctionScopeInfo to prevent that from happening. rdar://problem/39352313 Differential Revision: https://reviews.llvm.org/D51564

2018-10-01[X86] Improve test instruction shrinking when the sign flag is used and the ↵Craig Topper
output of the and is truncated Currently we skip looking through truncates if the sign flag is used. But that's overly restrictive. It's safe to look through the truncate as long as we ensure one of the 3 things when we shrink. Either the MSB of the mask at the shrunken size isn't set. If the mask bit is set then either the shrunk size needs to be equal to the compare size or the sign flag needs to be unused. There are still missed opportunities to shrink a load and fold it in here. This will be fixed in a future patch. Differential Revision: https://reviews.llvm.org/D52669

2018-10-01[InstCombine] Handle vector compares in foldGEPIcmp(), take 2Jesper Antonsson
Summary: This is a continuation of the fix for PR34627 "InstCombine assertion at vector gep/icmp folding". (I just realized bugpoint had fuzzed the original test for me, so I had fixed another trigger of the same assert in adjacent code in InstCombine.) This patch avoids optimizing an icmp (to look only at the base pointers) when the resulting icmp would have a different type. The patch adds a testcase and also cleans up and shrinks the pre-existing test for the adjacent assert trigger.

2018-10-01[InstCombine] try to convert vector insert+extract to trunc; 2nd trySanjay Patel
This was originally committed at rL343407, but reverted at rL343458 because it crashed trying to handle a case where the destination type is FP. This version of the patch adds a check for that possibility. Tests added at rL343480. Original commit message: This transform is requested for the backend in: https://bugs.llvm.org/show_bug.cgi?id=39016 ...but I figured it was worth doing in IR too, and it's probably easier to implement here, so that's this patch. In the simplest case, we are just truncating a scalar value. If the extract index doesn't correspond to the LSBs of the scalar, then we have to shift-right before the truncate. Endian-ness makes this tricky, but hopefully the ASCII-art helps visualize the transform. Differential Revision: https://reviews.llvm.org/D52439

It'd save waiting time for clangd developers. check-clangd (build ~1000 files, run ~340 tests) vs check-clang-tools (build ~3000 files, run ~1000 tests).
