2020-03-26Really fix og9 "Fix hang when running oacc exec with CUDA 9.0 nvprof"devel/omp/gcc-9Thomas Schwinge2-4/+13
In my yesterday's commit 9ae129017c7fc1fa638d6beedd3802b515ca692b 'Fix og9 "Fix hang when running oacc exec with CUDA 9.0 nvprof"', I wrongly blamed the og9 "Fix hang when running oacc exec with CUDA 9.0 nvprof" to be responsible for the hang being back, when in fact it's only the later og9 "OpenACC Profiling Interface (incomplete)" backport from trunk that introduced the problem. The confusing thing was that the og9 "Fix hang when running oacc exec with CUDA 9.0 nvprof" commit appears *before* the og9 "OpenACC Profiling Interface (incomplete)" backport that it relates to. And, in addition to that, I pushed the wrong (incomplete) version of my fix. libgomp/ * oacc-init.c (acc_init_1): Move other 'acc_init_state' logic to where it belongs.
2020-03-25Fix og9 "Fix hang when running oacc exec with CUDA 9.0 nvprof"Thomas Schwinge2-5/+10
Compared to the original og7 version, and still-good og8 version, the og9 version of this patch did get its code altered in a way so that it no longer resolves the problem it's meant to resolve -- the hang was back. libgomp/ * oacc-init.c (acc_init_1): Move 'acc_init_state' logic to where it belongs.
