Subject: [RFC][PATCH 16/X][libsanitizer] Build libhwasan with interceptors
Date: Fri, 06 Sep 2019 14:47:00 -0000 [thread overview]
Message-ID: <VI1PR08MB5471DADB5FFB6D5F624A0D4AE0BA0@VI1PR08MB5471.eurprd08.prod.outlook.com> (raw)
In-Reply-To: <156778058239.16148.17480879484406897649.scripted-patch-series@arm.com>
[-- Attachment #1: Type: text/plain, Size: 2267 bytes --]
This builds the library in the way designed for userspace rather than
for kernel space. This means intercepting allocation routines so they
now tag memory at the same time, and intercepting setjmp/longjmp so that
it clears tags on the stack when called.
libsanitizer/ChangeLog:
2019-09-06 Matthew Malcomson <matthew.malcomson@arm.com>
* hwasan/Makefile.am: Set HWASAN_WITH_INTERCEPTORS macro.
* hwasan/Makefile.in: Regenerate.
