X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5a50aed32ab80022a592091af011f6f0429d269a;p=gcc.git [Darwin, fixincludes] Fix Darwin9/10 math.h issues. Darwin has had long long functions for some considerable time and these are exposed in Darwin8 and Darwin11+ headers. However, for some reason it was elected to hide them behind __STRICT_ANSI__ and __STDC_VERSION__ on Darwin9 and Darwin10. This is a problem for G++/libstdc++ that expects the functions to be available for strict ansi (-std=c++14, for example) and without defining __STDC_VERSION__. The fix here follows the pattern used in Darwin11+ headers where the functions may be explicitly hidden by defining __DARWIN_NO_LONG_LONG. This fixes the tr1 testsuite fails seen on Darwin9 and 10. 2019-06-21 Iain Sandoe * inclhack.def: Replace the complex test using __STRICT_ANSI__ and __STDC_VERSION__ with a test using __DARWIN_NO_LONG_LONG. Ensure that the top level math.h uses <> to wrap included headers rather than "". * fixincl.x: Regenerated. * tests/base/architecture/ppc/math.h: Update test to include the __DARWIN_NO_LONG_LONG case.
