# PowerPC64 ELFv2 ABI 4/6: Stack frame layout changes
|
|
|
5de29b |
#
|
|
|
5de29b |
# This updates glibc for the changes in the ELFv2 relating to the
|
|
|
5de29b |
# stack frame layout. These are described in more detail here:
|
|
|
5de29b |
# http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01149.html
|
|
|
5de29b |
# http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01146.html
|
|
|
5de29b |
#
|
|
|
5de29b |
# Specifically, the "compiler and linker doublewords" were removed,
|
|
|
5de29b |
# which has the effect that the save slot for the TOC register is
|
|
|
5de29b |
# now at offset 24 rather than 40 to the stack pointer.
|
|
|
5de29b |
#
|
|
|
5de29b |
# In addition, a function may now no longer necessarily assume that
|
|
|
5de29b |
# its caller has set up a 64-byte register save area its use.
|
|
|
5de29b |
#
|
|
|
5de29b |
# To address the first change, the patch goes through all assembler
|
|
|
5de29b |
# files and replaces immediate offsets in instructions accessing the
|
|
|
5de29b |
# ABI-defined stack slots by symbolic offsets. Those already were
|
|
|
5de29b |
# defined in ucontext_i.sym and used in some of the context routines,
|
|
|
5de29b |
# but that doesn't really seem like the right place for those defines.
|
|
|
5de29b |
#
|
|
|
5de29b |
# The patch instead defines those symbolic offsets in sysdeps.h,
|
|
|
5de29b |
# in two variants for the old and new ABI, and uses them systematically
|
|
|
5de29b |
# in all assembler files, not just the context routines.
|
|
|
5de29b |
#
|
|
|
5de29b |
# The second change only affected a few assembler files that used
|
|
|
5de29b |
# the save area to temporarily store some registers. In those
|
|
|
5de29b |
# cases where this happens within a leaf function, this patch
|
|
|
5de29b |
# changes the code to store those registers to the "red zone"
|
|
|
5de29b |
# below the stack pointer. Otherwise, the functions already allocate
|
|
|
5de29b |
# a stack frame, and the patch changes them to add extra space in
|
|
|
5de29b |
# these frames as temporary space for the ELFv2 ABI.
|
|
|
