2013-10-30Move global FlagSfi variables to common modulePetar Jovanovic
When built as nexe, llc is configured and built for one arch only. Variables FlagSfiData, FlagSfiLoad, FlagSfiStore, FlagSfiStack, and FlagSfiBranch have to availabe for MIPS as well, so this change moves them from ARM-only code to common code.

2013-07-11Sandbox ARM load/store exclusive dualJF Bastien
PNaCl's LLVM sandboxing wasn't correct for ARM load/store exclusive dual. I encountered this while running our testsuite with my atomic changes: the tests which use volatile 64-bit values started failing validation. R=dschuff@chromium.org BUG= validation failure TEST= ./pnacl/test.sh test-arm Review URL: https://codereview.chromium.org/18978015

2012-11-29Disable register-register preloads for NaCl.JF Bastien
This disables, prefetches using the base reg + index reg ("[rb, ri]") style addressing mode. We do not allow this addressing mode for other memory instructions either and just to make sure we would also like to sandbox this instruction which is only possible for the base + immediate offset addressing mode.

2012-10-31llvm: build with fewer warningsJan Voung
Warnings: unused variables, unused functions, -Wreorder, and remember to return a value in a non-void function. Also remove setjmp/longjmp intrinsics for x86, which aren't being used now (no equivalents in ARM and no equivalent for x86-64 with the zero-based sandbox, etc.). This exposes a few more unused functions. BUG= none TEST= test-all Review URL: https://codereview.chromium.org/11345016
