Tobias Grosser	2fb847fbf6	[GPGPU] Set Polly's RTC to false in case invariant load hoisting fails This matches the behavior we already have in lib/Codegen/CodeGeneration.cpp and makes sure that we fall back to the original code. It seems when invariant load hoisting was introduced to the GPGPU backend we missed to reset the RTC flag, such that kernels where invariant load hoisting failed executed the 'optimized' SCoP, which however is set to a simple 'unreachable'. Unsurprisingly, this results in hard to debug issues that are a lot of fun to debug. llvm-svn: 314624	2017-10-01 12:39:14 +00:00

[GPGPU] Set Polly's RTC to false in case invariant load hoisting fails

This matches the behavior we already have in lib/Codegen/CodeGeneration.cpp and
makes sure that we fall back to the original code. It seems when invariant load
hoisting was introduced to the GPGPU backend we missed to reset the RTC flag,
such that kernels where invariant load hoisting failed executed the 'optimized'
SCoP, which however is set to a simple 'unreachable'. Unsurprisingly, this
results in hard to debug issues that are a lot of fun to debug.
