Subject: [Bug target/102215] New: [GCN offloading] Missing '__atomic_compare_exchange_1' etc.
Date: Mon, 06 Sep 2021 09:55:54 +0000 [thread overview]
Message-ID: <bug-102215-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102215
Bug ID: 102215
Summary: [GCN offloading] Missing '__atomic_compare_exchange_1'
etc.
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: openmp
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tschwinge at gcc dot gnu.org
CC: ams at gcc dot gnu.org, jakub at gcc dot gnu.org, jules at gcc dot gnu.org
Target Milestone: ---
Target: GCN
The recent commit 090f0d78f194e3cda23fe904016db77ea36c38fa "openmp: Improve
expand_omp_atomic_pipeline" regresses GCN offloading testing as follows:
[-PASS:-]{+FAIL:+} libgomp.c/../libgomp.c-c++-common/reduction-16.c (test
for excess errors)
[-PASS:-]{+UNRESOLVED:+} libgomp.c/../libgomp.c-c++-common/reduction-16.c
[-execution test-]{+compilation failed to produce executable+}
ld: error: undefined symbol: __atomic_compare_exchange_1
>>> referenced by /tmp/cce2YauE.o:(test_char._omp_fn.1)

collect2: error: ld returned 1 exit status
mkoffload: fatal error:

Similar for 'libgomp.c++/../libgomp.c-c++-common/reduction-16.c'.
And:
[-PASS:-]{+FAIL:+} libgomp.c/target-43.c (test for excess errors)
[-PASS:-]{+UNRESOLVED:+} libgomp.c/target-43.c [-execution
test-]{+compilation failed to produce executable+}
ld: error: undefined symbol: __atomic_compare_exchange_1
>>> referenced by /tmp/cc1Kwlmj.o:(main._omp_fn.0)
>>> referenced by /tmp/cc1Kwlmj.o:(main._omp_fn.0)
collect2: error: ld returned 1 exit status
mkoffload: fatal error:
[...]/gcc/x86_64-pc-linux-gnu-accel-amdgcn-amdhsa-gcc returned 1 exit status
These all do:
{ dg-additional-options "-foffload-options=nvptx-none=-latomic" { target {
offload_target_nvptx } } }
Do we now also need libatomic for GCN or should this be handled in the GCN back
end?
