Subject: [PATCH] Enable -Bsymbolic and -Bsymbolic-functions to PIE
|
|
|
|
Before binutils 2.26, -Bsymbolic and -Bsymbolic-functions were also
|
|
applied to PIE so that "ld -pie -Bsymbolic -E" can be used to export
|
|
symbols in PIE with local binding. This patch re-enables -Bsymbolic
|
|
and -Bsymbolic-functions for PIE.
