When using + generic dummy frames, don't attempt to write TOC value or + function to call into the call dummy. + (rs6000_push_arguments): Adapt USE_GENERIC_DUMMY_FRAMES + code to also handle the PowerOpen ABI. + (ppc_push_return_address): Enable for all ports. + * config/powerpc/tm-ppc-aix.h (USE_GENERIC_DUMMY_FRAMES, + PUSH_DUMMY_FRAME, PUSH_RETURN_ADDRESS, GET_SAVED_REGISTER, + CALL_DUMMY_BREAKPOINT_OFFSET, CALL_DUMMY_LOCATION, + CALL_DUMMY_ADDRESS, CALL_DUMMY_START_OFFSET): Override defaults + provided by generic RS6000 definitions so that call dummies + are implemented using generic dummy frames instead. + + * rs6000-nat.c (store_inferior_registers): Call exec_one_dummy_insn() + prior to changing the stack pointer via ptrace(). Also, ignore + attempts to store to undefined registers that are less than + NUM_REGS. + + * rs6000-tdep.c (DUMMY_FRAME_SIZE): Change size of the dummy + frame from 436 to 448 to account for alignment padding. + (rs6000_push_arguments): Obtain actual register size instead + of assuming the register is 4 bytes long. [There's still + more work to be done to totally remove the 4 byte assumption, + however.] Make sure the stack is 16 byte aligned as required + by the PowerOpen ABI. Also, make sure that small structures + passed in registers are properly aligned within the register. + +2000-02-15 Jesper Skov <jskov@cygnus.co.uk> + + Patch applied by Kevin Buettner <kevinb@redhat.com> + + * rs6000-tdep.c (skip_prologue): skip copying of argument + registers to local variable registers. + 2000-02-14 Jim Kingdon <kingdon@redhat.com> * elfread.c (elf_symtab_read): Revert changes by Amit S.
