The __cpu_indicator_init and __cpu_model symbols are not safe to use from shared libgcc_s.so from ifunc resolvers, so since gcc-6, only the definitions from static libgcc.a are used, however the symbols are kept in libgcc_s as well for backward compatibility (with appropriate symbol version). On targets without such backward compatibility concern add cpuinfo to the static library only (this avoids running the ctor, reduces libgcc_s size and elf abi concerns about the versioned symbols). libgcc/ 2016-11-11 Szabolcs Nagy <szabolcs.nagy@arm.com> * config.host (i[3456]86-*-musl*, x86_64-*-musl*): Use i386/t-cpuinfo-static instead of i386/t-cpuinfo. * config/i386/t-cpuinfo-static: New.

Add a little shell script to auto-generate runtime.sigtable from the known signal names. Force the main package to always import the runtime package. Otherwise some runtime package global variables may never be initialized. Set the syscallsp and syscallpc fields of g when entering a syscall, so that the runtime package knows when a g is executing a syscall. Fix runtime.funcPC to avoid dead store elimination of the interface value when the function is inlined. Reviewed-on: https://go-review.googlesource.com/33025 From-SVN: r242060

When combine splits a three-insn combination into two instructions it can reuse i2dest for the temporary result of the first new instruction. However all information it has in reg_stat about that register will be stale. This results in the simplify_gen_binary calls in change_zero_ext using out-of-date information, which makes it think one of the ANDs generated there always results in 0, and it doesn't get better from there. This can also happen if a splitter in the MD uses nonzero_bits (for example). I tried to make the splitting code in combine save and restore the i2dest reg_stat info, but that causes one of the acats tests to fail. This whole reg_stat thing needs an overhaul, and/or we shouldn't reuse i2dest for unrelated purposes when splitting. This patch changes change_zero_ext to do the expected simplifications itself and not call simplify_gen_*. PR rtl-optimization/78232 * combine.c (try_combine): Add a big comment about why reusing i2dest is undesirable. (change_zero_ext): Do not call simplify_gen_binary, do the simplifications manually.

Disable unnecessary calls to dwarf2out_decl for the parents of nested functions. This fixes a libstdc++ build regression on x86_64-apple-darwin, as these calls used to add duplicate attributes (for instance DW_AT_inline and DW_AT_object_pointer) to the corresponding DW_TAG_subprogram DIE.

match.pd transforms (A&C)|(B&~C) to ((A^B)&C)^B, which is fewer operations if C is not const (and it is not on simple tests at least, this transform is done very early already). Various processors have "insert" instructions that can do this, but combine cannot build those from the xor-and-xor, especially it has no chance at all to do that if A or B or multiple instructions as well (on PowerPC, the rl[wd]imi instructions can do this with together with a rotate, or a simple shift with appropriate C; other ISAs have similar insns). This patch makes RTL simplify transform (xor (and (xor A B) C) B) back to (ior (and A C) (and B ~C)) for constant C (and similar with A instead of B for that last term). * simplify-rtx.c (simplify_binary_operation_1): Simplify (xor (and (xor A B) C) B) to (ior (and A C) (and B ~C)) and (xor (and (xor A B) C) A) to (ior (and A ~C) (and B C)) if C is a const_int.
