# PowerPC ugly symbol versioning
|
|
|

|
|
|
5de29b |
# This patch fixes symbol versioning in setjmp/longjmp. The existing
|
|
|
5de29b |
# code uses raw versions, which results in wrong symbol versioning when
|
|
|
5de29b |
# you want to build glibc with a base version of 2.19 for LE.
|
|
|
5de29b |
#
|
|
|
5de29b |
# Note that the merging the 64-bit and 32-bit versions in novmx-lonjmp.c
|
|
|
5de29b |
# and pt-longjmp.c doesn't result in GLIBC_2.0 versions for 64-bit, due
|
|
|
5de29b |
# to the base in shlib_versions.
|
|
|
5de29b |
#
|
|
|
5de29b |
# * sysdeps/powerpc/longjmp.c: Use proper symbol versioning macros.
|
|
|

# * sysdeps/powerpc/novmx-longjmp.c: Likewise.
