From 3b16c5514a2e01d47295e8d82cecd6b62db62955 Mon Sep 17 00:00:00 2001 From: Maxim Ostapenko Date: Sat, 28 Nov 2015 16:39:32 +0000 Subject: libsanitizer merge from upstream r250806, compiler part. gcc/ * asan.c (asan_emit_stack_protection): Don't pass local stack to asan_stack_malloc_[n] anymore. Check if asan_stack_malloc_[n] returned NULL and use local stack than. (asan_finish_file): Insert __asan_version_mismatch_check_v[n] call in addition to __asan_init. * sanitizer.def (BUILT_IN_ASAN_INIT): Rename to __asan_init. (BUILT_IN_ASAN_VERSION_MISMATCH_CHECK): Add new builtin call. * asan.h (asan_intercepted_p): Handle new string builtins. * ubsan.c (ubsan_use_new_style_p): New function. (ubsan_instrument_float_cast): If location is unknown, assign input_location to loc. Propagate loc to ubsan_create_data if ubsan_use_new_style_p returned true. config/ * bootstrap-asan.mk: Replace ASAN_OPTIONS=detect_leaks with LSAN_OPTIONS=detect_leaks. gcc/testsuite/ * c-c++-common/ubsan/float-cast-overflow-10.c: Adjust test. * c-c++-common/ubsan/float-cast-overflow-8.c: Likewise. * c-c++-common/ubsan/float-cast-overflow-9.c: Likewise. * g++.dg/asan/default-options-1.C: Likewise. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@229112 138bc75d-0d04-0410-961f-82ee72b054a4 --- config/ChangeLog | 5 +++++ config/bootstrap-asan.mk | 2 +- 2 files changed, 6 insertions(+), 1 deletion(-) (limited to 'config') diff --git a/config/ChangeLog b/config/ChangeLog index 6847cb9..d115579 100644 --- a/config/ChangeLog +++ b/config/ChangeLog @@ -1,3 +1,8 @@ +2015-10-21 Maxim Ostapenko + + * bootstrap-asan.mk: Replace ASAN_OPTIONS=detect_leaks with + LSAN_OPTIONS=detect_leaks. + 2015-08-24 Yaakov Selkowitz * iconv.m4 (AM_ICONV_LINK): Use in-tree libiconv when present. diff --git a/config/bootstrap-asan.mk b/config/bootstrap-asan.mk index 52ef30e..70baaf9 100644 --- a/config/bootstrap-asan.mk +++ b/config/bootstrap-asan.mk @@ -1,7 +1,7 @@ # This option enables -fsanitize=address for stage2 and stage3. # Suppress LeakSanitizer in bootstrap. -export ASAN_OPTIONS="detect_leaks=0" +export LSAN_OPTIONS="detect_leaks=0" STAGE2_CFLAGS += -fsanitize=address STAGE3_CFLAGS += -fsanitize=address -- cgit v1.1
