From: Matthew Malcomson Date: Wed, 25 Nov 2020 16:31:39 +0000 (+0000) Subject: libsanitizer: Only build libhwasan when targeting AArch64 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8a769f816f8af7a8aac6f16874011c3e15280e38;p=gcc.git libsanitizer: Only build libhwasan when targeting AArch64 Though the library has limited support for x86, we don't have any support for generating code targeting x86 so there is no point building for that target. Ensure we build for AArch64 but not for AArch64 ilp32. libsanitizer/ChangeLog: * Makefile.am: Condition Build hwasan directory. * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac: Set HWASAN_SUPPORTED based on target architecture. * configure.tgt: Likewise. --- diff --git a/libsanitizer/Makefile.am b/libsanitizer/Makefile.am index 2a7e8e1debe..065a65e78d4 100644 --- a/libsanitizer/Makefile.am +++ b/libsanitizer/Makefile.am @@ -14,7 +14,7 @@ endif if LIBBACKTRACE_SUPPORTED SUBDIRS += libbacktrace endif -SUBDIRS += lsan asan ubsan hwasan +SUBDIRS += lsan asan ubsan nodist_saninclude_HEADERS += \ include/sanitizer/lsan_interface.h \ include/sanitizer/asan_interface.h \ @@ -23,6 +23,9 @@ nodist_saninclude_HEADERS += \ if TSAN_SUPPORTED SUBDIRS += tsan endif +if HWASAN_SUPPORTED +SUBDIRS += hwasan +endif endif ## May be used by toolexeclibdir. diff --git a/libsanitizer/Makefile.in b/libsanitizer/Makefile.in index 2c57d49cbff..3873ea4d705 100644 --- a/libsanitizer/Makefile.in +++ b/libsanitizer/Makefile.in @@ -97,6 +97,7 @@ target_triplet = @target@ @SANITIZER_SUPPORTED_TRUE@@USING_MAC_INTERPOSE_FALSE@am__append_2 = interception @LIBBACKTRACE_SUPPORTED_TRUE@@SANITIZER_SUPPORTED_TRUE@am__append_3 = libbacktrace @SANITIZER_SUPPORTED_TRUE@@TSAN_SUPPORTED_TRUE@am__append_4 = tsan +@HWASAN_SUPPORTED_TRUE@@SANITIZER_SUPPORTED_TRUE@am__append_5 = hwasan subdir = .
