Hi,
g++.dg/ext/arm-fp16/fp16-mangle-1.C is failed because GCC now sets
DECL_COMDAT on template instantiations if flag_implicit_templates is in
effect. Then DECL_WEAK will be set accordingly. As a result, checking for
".global xxxx" would fail on this case.
This patch fixes this by relaxing scanning string into ".global|weak xxxx"
just in case it's still global if some options are specified explicitly.
Since the change is made by
https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213307.
Hi Jason, could you help me here that I understood the issue correctly?
Thanks very much.
Thanks,
