2020-05-01gcc: Enable bits for sanitizer support on FreeBSD x86_64Andreas Tobler
This patch add the necessary bits to suport libasan on FreeBSD x86_64. gcc * config/i386/i386.h: Define a new macro: SUBTARGET_SHADOW_OFFSET. * config/i386/i386.c (ix86_asan_shadow_offset): Use this macro. * config/i386/darwin.h: Override the SUBTARGET_SHADOW_OFFSET macro. * config/i386/freebsd.h: Likewise. * config/freebsd.h (LIBASAN_EARLY_SPEC): Define. LIBTSAN_EARLY_SPEC): Likewise. (LIBLSAN_EARLY_SPEC): Likewise. libsanitizer: * configure.tgt: Add x86_64- and i?86-*-freebsd* targets.
2020-03-01Darwin, libsanitizer: Adjust minimum supported Darwin version (PR93731).Iain Sandoe
The current imported libsanitizer code produces kernel panics for Darwin 11 (macOS 10.7) and is unsupported for earlier versions already. It is not clear if the current sources are even intended to be supported on Darwin 11, so this patch causes the default to be build without sanitizers for Darwin <= 11. 2020-03-01 Iain Sandoe <iain@sandoe.co.uk> PR sanitizer/93731 * configure.tgt (x86_64-*-darwin*, i?86-*-darwin*): Enable by default only for Darwin versions greater than 12 (macOS 10.8).
2020-03-01[Darwin, libsanitizer] Default to no sanitizer for Darwin <= 10Iain Sandoe
Darwin10 is no longer supported upstream and will not build without additional patches.

2019-09-10[ARM/FDPIC v6 03/24] [ARM] FDPIC: Force FDPIC related options unless ↵Christophe Lyon
-mno-fdpic is provided In FDPIC mode, we set -fPIE unless the user provides -fno-PIE, -fpie, -fPIC or -fpic: indeed FDPIC code is PIC, but we want to generate code for executables rather than shared libraries by default. We also make sure to use the --fdpic assembler option, and select the appropriate linker emulation. At link time, we also default to -pie, unless we are generating a shared library or a relocatable file (-r). Note that static link is not supported as it requires specifying the dynamic linker because the executable still has to relocate itself at startup. We also force 'now' binding since lazy binding is not supported. We should also apply the same behavior for -Wl,-Ur as for -r, but I couldn't find how to describe that in the specs fragment. 2019-09-10 Christophe Lyon <christophe.lyon@st.com> Mickaël Guêné <mickael.guene@st.com> gcc/ * config.gcc: Handle arm*-*-uclinuxfdpiceabi. * config/arm/bpabi.h (TARGET_FDPIC_ASM_SPEC): New.
