Subject: amdgcn, nvptx: Handle -fpic/-fPIC in mkoffload
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a8b522311beef5e02de15427e924752ea02def2a;p=gcc.git

amdgcn, nvptx: Handle -fpic/-fPIC in mkoffload

2020-07-08  Tobias Burnus  <tobias@codesourcery.com>

gcc/ChangeLog:

	* config/gcn/mkoffload.c (compile_native, main): Pass -fPIC/-fpic
	on to the native compiler, if used.
	* config/nvptx/mkoffload.c (compile_native, main): Likewise.
