Description Józef Kucia 2017-10-09 18:59:22 UTC 
OpAtomicIDecrement should return the original value. Anvil seems to return the decremented value.

There was also a similar bug in glslang: https://github.com/KhronosGroup/glslang/issues/1067
Comment 1 Jason Ekstrand 2017-10-09 20:41:44 UTC 
Could you please provide some sort of test case?
Comment 2 Józef Kucia 2017-10-11 22:09:53 UTC 
OpAtomicIDecrement actually returns the correct value. I had an error in my test case. Sorry for the noise.
