* [asan] Add fallback for Thumb after r350139Diana Picus2019-01-143-2/+13
| | | | | | | | | | | | | | This reverts r350806 which marked some tests as UNSUPPORTED on ARM and instead reintroduces the old code path only for Thumb, since that seems to be the only target that broke. It would still be nice to find the root cause of the breakage, but with the branch point for LLVM 8.0 scheduled for next week it's better to put things in a stable state while we investigate.

* Detect incorrect FileCheck variable CLI definitionThomas Preud'homme2019-01-142-9/+43
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: While the backend code of FileCheck relies on definition of variable from the command-line to have an equal sign '=' and a variable name before that, the frontend does not actually enforce it. This leads to FileCheck crashing when invoked with invalid syntax for the -D option. This patch adds the missing validation in the frontend. It also makes the -D option an AlwaysPrefix option to be able to detect -D=FOO as being a define without variable and -D as missing its value.

* Add support for prefix-only CLI optionsThomas Preud'homme2019-01-143-8/+95
| | | | | | | | | | | | | | | | | | | | | | Summary: Add support for options that always prefix their value, giving an error if the value is in the next argument or if the option is given a value assignment (ie. opt=val). This is the desired behavior for the -D option of FileCheck for instance.

* [OpenMP] Fix LIBOMP_USE_DEBUGGER=ON build (PR38612)Roman Lebedev2019-01-133-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Two things: 1. Those two variables had the wrong sigdness, which was resulting in "sign mismatch in comparison" warning. 2. The whole `kmp_debugger.cpp` wasn't being built, or rather, it was being built as-if `USE_DEBUGGER` was off, thus, nothing provided the definition of `__kmp_omp_debug_struct_info`, `__kmp_debugging`. Makes sense, because `USE_DEBUGGER` is set in `kmp_config.h`, which is not included explicitly. It is included by `kmp.h`, but that one is only included inside of the `#if USE_DEBUGGER` block.. I *think* this is the only source file with this issue, everything else seem to `#include` either `kmp.h` or `kmp_config.h`. The alternative solution would be to add `add_compile_options(-include kmp_config.h)` in CMake. I did verify that `__kmp_omp_debug_struct_info` becomes available with this patch.

| | | | | | | | | | MIPS `jr` instruction uses a delay-slot.

* [ORC][MIPS] Setup t9 register and call function through this registerSimon Atanasyan2019-01-122-13/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MIPS ABI states that every function must be called through jalr $t9. In other words, a function expect that t9 register points to the beginning of its code. A function uses this register to calculate offset to the Global Offset Table and save it to the `gp` register. ``` lui $gp, %hi(_gp_disp) addiu $gp, %lo(_gp_disp) addu $gp, $gp, $t9 ``` If `t9` and as a result `$gp` point to the wrong place the following code loads incorrect value from GOT and passes control to invalid code. ``` lw $v0,%call16(foo)($gp) jalr $t9 ``` OrcMips32 and OrcMips64 writeResolverCode methods pass control to the resolved address, but do not setup `$t9` before the call. The `t9` holds value of the beginning of `resolver` code so any attempts to call routines via GOT failed. This change fixes the problem. The `OrcLazy/hidden-visibility.ll` test starts to pass correctly. Before the change it fails on MIPS because the `exitOnLazyCallThroughFailure` called from the resolver code could not call libc routine `exit` via GOT.

Especially in combination with the deep lattice, this may cause instructions too be recomputed very often. To avoid this, switch to a SetVector.

But we can't represent this with a vselect like we normally do. This also avoids the need to have a special X86ISD::SELECT when avx512bw isn't enabled since vselect v8i16 isn't legal there. Fixes another instruction for PR34877. llvm-svn: 350994
