2018-05-03[tree-complex.c] PR tree-optimization/70291: Inline floating-point complex ↵Kyrylo Tkachov5-42/+184
multiplication more aggressively We can improve the performance of complex floating-point multiplications by inlining the expansion a bit more aggressively. We can inline complex x = a * b as: x = (ar*br - ai*bi) + i(ar*bi + br*ai); if (isunordered (__real__ x, __imag__ x)) x = __muldc3 (a, b); //Or __mulsc3 for single-precision That way the common case where no NaNs are produced we can avoid the libgcc call and fall back to the NaN handling stuff in libgcc if either components of the expansion are NaN. The implementation is done in expand_complex_multiplication in tree-complex.c and the above expansion will be done when optimising for -O1 and greater and when not optimising for size. At -O0 and -Os the single call to libgcc will be emitted. For the code: __complex double foo (__complex double a, __complex double b) { return a * b; } We will now emit at -O2 for aarch64: foo: fmul d16, d1, d3 fmul d6, d1, d2 fnmsub d5, d0, d2, d16 fmadd d4, d0, d3, d6 fcmp d5, d4 bvs .L8 fmov d1, d4 fmov d0, d5 ret .L8: stp x29, x30, [sp, -16]! mov x29, sp bl __muldc3 ldp x29, x30, [sp], 16 ret Instead of just a branch to __muldc3.

2018-05-02libgo: add type/const references to sysinfo.cIan Lance Taylor1-1/+1
This patch adds explicit references to various types and constants defined by the header files included by sysinfo.c (used to drive the generation of gen-sysinfo.go as part of the libgo build via the GCC "-fdump-go-spec" option). The intent is to enable clients to gather the same info generated by "-fdump-go-spec" by instead reading the generated DWARF from a sysinfo.o object file compiled with "-g". Some compilers (notably clang) try to omit DWARF records for a given type unless there is an explicit use of it in the translation unit; the additional references are to insure that everything we want to see in the DWARF shows up.

2018-04-30Use char_span for return type of location_get_source_lineDavid Malcolm11-123/+176
location_get_source_line returns a const char * that isn't 0-terminated, writing back a length through an int * param. This is error-prone, as all call-sites have to take into account the lack of 0-termination, and respect the length of the buffer. It's cleaner to bundle together this pointer+length state into a class, so this patch does so, reusing the "char_span" class that I introduced in r250187 (as part of the fix for PR c/81405). The patch also adds assertions to all access to the char_span. gcc/c-family/ChangeLog: * c-format.c (get_corrected_substring): Update for location_get_source_line returning a char_span. Use a char_span when handling the prefix of the correction. * c-indentation.c (get_visual_column): Update for location_get_source_line returning a char_span.
