libsanitizer in gcc fails to build on PowerPC with gcc versions 4.9 and 5.x used in conjunction with glibc 2.25, with the following error: ../../../../gcc-host/libsanitizer/asan/asan_linux.cc: In function 'bool __asan::AsanInterceptsSignal(int)': ../../../../gcc-host/libsanitizer/asan/asan_linux.cc:222:20: error: 'SIGSEGV' was not declared in this scope return signum == SIGSEGV && common_flags()->handle_segv; This commit adds a patch that has been submitted to upstream gcc (https://patchwork.ozlabs.org/patch/725596/) but not merged. The patch is no longer needed with gcc 6.x and later because the code has been reworked.

Subject: [PATCH] asan: fix missing include of signal.h
|
|
|
|
This breaks when building gcc 4.9.4 / 5.4.0 with
|
|
target_platform=powerpc-unknown-linux-gnu with glibc 2.25:
|
|
|
|
../../../../gcc-host/libsanitizer/asan/asan_linux.cc: In function 'bool __asan::AsanInterceptsSignal(int)':
|
|
../../../../gcc-host/libsanitizer/asan/asan_linux.cc:222:20: error: 'SIGSEGV' was not declared in this scope
|
|
return signum == SIGSEGV && common_flags()->handle_segv;
|
|
|
|
This has been verified to apply to at least 4.9.4 and up to 5.4,
|
|
the code has been reworked for gcc 6.
