Bug ID: 113331
Summary: AMDGCN: Compilation failure due to duplicate
.LEHB<n>/.LEHE<n> symbols
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org

Test case
The attached file fails to compile with AMD GCN offloading on current mainline.
It also fails on GCC 13.2.0 as packaged in Debian, so this doesn't appear to be
a regression.
$ g++ -fopenmp -foffload=amdgcn-amdhsa -save-temps dup-syms.cc -o dup-syms
./dup-syms.xamdgcn-amdhsa.mkoffload.2.s:256:1: error: symbol '.LEHB0' is
already defined
.LEHB0:
^
./dup-syms.xamdgcn-amdhsa.mkoffload.2.s:258:1: error: symbol '.LEHE0' is
already defined
.LEHE0:
^
./dup-syms.xamdgcn-amdhsa.mkoffload.2.s:288:1: error: symbol '.LEHB1' is
already defined
.LEHB1:
^
./dup-syms.xamdgcn-amdhsa.mkoffload.2.s:290:1: error: symbol '.LEHE1' is
already defined
.LEHE1:
^
The test case doesn't trigger with NVPTX offloading, but I don't think that
definitely implies that this is something GCN-specific (vs. generically
offload-related).
