Module Name: src
Committed By: christos
Date: Tue Apr 2 03:01:50 UTC 2019
Modified Files:
src/external/gpl3/gcc/dist/gcc/config/vax: vax.c
Log Message:
Compiling some files with -fPIC and -O2 ends up having global
symbols classified as local in pic mode, and that ends up with PC32
relocations "movl *psp, %rx" (/bin/sh parse.c). Treat pic code as
shared libraries to avoid classifying common initialized symbols
as local. Thanks to thorpej@ for his help.
