...ng: 292141 from January 16, 2017
- Compiler-RT: 291346 from January 7, 2017
The patched compiler was built with the current posted versions of my
patches applied on top of the SVN IDs listed above.
The following compiler settings in the SPEC CPU2006 cfg files were used
for each configuration:
COPTIMIZE:
- Unpatched Base: -std=gnu89 -O2 -fno-strict-aliasing -march=skylake
-mtune=skylake
- Unpatched/Patched SafeStack: -std=gnu89 -O2 -fno-strict-aliasing
-march=skylake -mtune=skylake -fsanitize=safe-stack
- MPX: -std=gnu89 -O2 -fno-strict-aliasing -march=skylake -mtune=skylake
-mseparate-stack...

AddressSanitizer on SPECCPU2006
Hi
I am using SanitizerCoverage feature supported by clang to get the
basicblock coverage.
my tested binaries are spec cpu2006. I compiled the binary with the option
COPTIMIZE = -O0 -fsanitize=address -fsanitize-coverage=bb -flto
-fno-strict-aliasing -std=gnu89 -gdwarf-3
After the compiling process is end. I run the 400.perlbench. with the
command
ASAN_OPTIONS=coverage=1 ./perlbench. However, the AddressSanitizer detect
the global buffer overflow and I could not run...

[RFC] Using Intel MPX to harden SafeStack
Hi,
I previously posted about using 32-bit X86 segmentation to harden SafeStack: http://lists.llvm.org/pipermail/llvm-dev/2016-May/100346.html That involves lowering the limits of the DS and ES segments that are used for ordinary data accesses while leaving the limit for SS, the stack segment, set to its maximum value. The safe stacks were clustered above the limits of DS and ES. Thus, by
