* config/mips/mips.c (mips_compute_frame_info): Initialise
args_size and hard_frame_pointer_offset fields of the frame
structure before calling mips_global_pointer.
It seems at some point the .size hook was hijacked to emit some
machine-specific directives, and the actual .size directive was
forgotten. This caused problems for split-stack support, since
linker couldn't scan the function body for non-split-stack calls.
gcc/ChangeLog:
* config/s390/s390.c (s390_asm_declare_function_size): Add code
to actually emit the .size directive.
S/390: Use proper read-only data section for literals.
Previously, .rodata was hardcoded. For C++ vague linkage functions,
this resulted in needlessly duplicated literals. With the new split
stack support, this resulted in link errors, due to .rodata containing
relocations to the discarded text sections.
gcc/ChangeLog:
* config/s390/s390.md (pool_section_start): Use switch_to_section
to select proper read-only data section instead of hardcoding .rodata.
