2018-10-23[arm] Update default CPUs during configureRichard Earnshaw
There are a couple of places in config.gcc where the default CPU is still arm6, but that was removed as a supported CPU earlier this year. This patch fixes those entries. The default CPU for configurations that do not explicitly set a default is now arm7tdmi (so assumes thumb is available). Given that StrongArm is on the deprecated list, this is a better default than we had previously. For NetBSD the default is StrongArm; this is the only remaining port that uses the old ABI and really still carries support for non-thumb based targets. PR target/86383 * config.gcc (arm*-*-netbsdelf*): Default to StrongARM if no CPU specified to configure.

2018-10-23 compiler: export indexed type data, read unexported types lazilyIan Lance Taylor
Introduce a new "types" command to the export data to record the number of types and the size of their export data. It is immediately followed by new "type" commands that can be indexed. Parse all the exported types immediately so that we register them, but parse other type data only as needed.

2018-10-22combine: Do not combine moves from hard registersSegher Boessenkool
On most targets every function starts with moves from the parameter passing (hard) registers into pseudos. Similarly, after every call there is a move from the return register into a pseudo. These moves usually combine with later instructions (leaving pretty much the same instruction, just with a hard reg instead of a pseudo). This isn't a good idea. Register allocation can get rid of unnecessary moves just fine, and moving the parameter passing registers into many later instructions tends to prevent good register allocation. This patch disallows combining moves from a hard (non-fixed) register. This also avoid the problem mentioned in PR87600 #c3 (combining hard registers into inline assembler is problematic). Because the register move can often be combined with other instructions *itself*, for example for setting some condition code, this patch adds extra copies via new pseudos after every copy-from-hard-reg. On some targets this reduces average code size. On others it increases it a bit, 0.1% or 0.2% or so. (I tested this on all *-linux targets). PR rtl-optimization/87600 * combine.c: Add include of expr.h. (cant_combine_insn_p): Do not combine moves from any hard non-fixed register to a pseudo. (make_more_copies): New function, add a copy to a new pseudo after the moves from hard registers into pseudos. (rest_of_handle_combine): Declare rebuild_jump_labels_after_combine later.

2018-10-22Don't double-count early-clobber matches.Andrew Stubbs
Given a pattern with a number of operands: (match_operand 0 "" "=&v") (match_operand 1 "" " v0") (match_operand 2 "" " v0") (match_operand 3 "" " v0") GCC will currently increment "reject" once, for operand 0, and then decrement it once for each of the other operands, ending with reject == -2 and an assertion failure. If there's a conflict then it might try to decrement reject yet again. Incidentally, what these patterns are trying to achieve is an allocation in which operand 0 may match one of the other operands, but may not partially overlap any of them. Ideally there'd be a better way to do this. In any case, it will affect any pattern in which multiple operands may (or must) match an early-clobber operand. The patch only allows a reject-- when one has not already occurred, for that operand. 2018-10-22 Andrew Stubbs <ams@codesourcery.com> gcc/ * lra-constraints.c (process_alt_operands): New local array, matching_early_clobber.
