Subject: * config/i386/tm-i386.h (PARM_BOUNDARY, CALL_DUMMY,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8758dec1c5c5119a4f9cb59da8375596f0314f94;p=binutils-gdb.git

* config/i386/tm-i386.h (PARM_BOUNDARY, CALL_DUMMY,
CALL_DUMMY_LENGTH, CALL_DUMMY_START_OFFSET,
CALL_DUMMY_BREAKPOINT_OFFSET, FIX_CALL_DUMMY): Remove defines.
(i386_fix_call_dummy): Remove prototype.
* i386-tdep.c (i386_call_dummy_words): New variable.
(i386_gdbarch_init): Adjust for removal of the
macros mentioned above.
