ChangeLog
Thu Jun 17 15:06:10 PDT 1999 Don Lindsay <dlindsay@cygnus.com>
* added support for -mpcrel (PC relative addressing for m68k)
based on code done by Michael Tiemann <tiemann@axon.cygnus.com>.
* invoke.texi (m68000 options): Add documentation for -mpcrel flag.
* m68k.c (print_operand_address): Handle 32-bit PIC case.
(comments for general_src_operand): Add some explanation
about EXTRA_CONSTRAINTS.
(OVERRIDE_OPTIONS): Enable -fPIC in combination with -mpcrel.
* m68kelf.h (OVERRIDE_OPTIONS): Ditto.
(LEGITIMATE_PIC_OPERAND_P): Fix typo.
(LEGITIMATE_PIC_OPERAND_P): Re-derive from m68k.h case.
* m68k.h (LEGITIMATE_PIC_OPERAND_P): Fix delete-o.
(INDIRECTABLE_1_ADDRESS): Delete spurious '/' at end of macro.
(OVERRIDE_OPTIONS): Change behavior so that -mpcrel implies -fpic
if not already set.
(OVERRIDE_OPTIONS): Merge in changes from m68k.h.
* m68k.h (TARGET_PCREL): New target flag.
(TARGET_SWITCHES): Add "pcrel" as a recognized switch.
(OVERRIDE_OPTIONS): Add checks for -mpcrel.
(LEGITIMATE_PIC_OPERAND_P): Don't normally accept anything that
contains a SYMBOL_REF. Relax this constraint during reload, since
we want to use the predicates, not reload's built-in concept of a
valid memory address, to control what insns need reloading.
(EXTRA_CONSTRAINT): Define constraints to accept pc-relative
operands (essentially 'g', 'm', and 's' under normal circumstances).
* m68k.c (print_operand): Cause printing of pc-relative addresses
to include pc register.
(print_operand_address): Ditto.
(general_src_operand): Accept operands that are not only
general_operands, but are also valid when used as a pc-relative
source.
(nonimmediate_src_operand): Similar, for nonimmediate_operands.
(memory_src_operand): Similar, for memory_operands.
(pcrel_address): New predicate to accept the special case of a
pc-relative address.
* m68k.md (many patterns): Rewrite common SImode, HImode, and
QImode insns to accept *_src_operand instead of *_operand where
pc-relative operands can fit. For example, a pc-relative operand
can be used as a memory source operand for addsi3, but not as a
memory destination.
* hp320.h linux.h m68kv4.h (LEGITIMATE_PIC_OPERAND_P) as in m68k.h.

* config.guess (ppc-*-linux-gnu): Also use ld emul elf32ppclinux.
