* version.c: Bump for snapshot.
Sun Aug 23 00:47:52 1998 Jeffrey A Law (law@cygnus.com)
* regmove.c (optimize_reg_copy_3): Disable for egcs-1.1.
Thu Aug 20 13:56:53 1998 Michael Meissner <meissner@cygnus.com>
* config/i386/winnt.c: Include system.h, not stdio.h to get
sys/param.h pulled in before rtl.h in case the system defines MIN
and MAX.
Wed Aug 19 21:33:19 1998 David Edelsohn <edelsohn@mhpcc.edu>
* rs6000.c (rs6000_output_load_toc_table): Use ld for 64-bit.
(output_toc): Use single TOC slot or llong minimal-toc for DFmode
and DImode 64-bit. Use llong for minimal-toc SFmode and
SYMBOL_REF / LABEL_REF 64-bit.
(output_function_profiler): Use llong for profiler label and ld to
load 64-bit label address.
Tue Aug 18 23:48:30 1998 Richard Henderson <rth@cygnus.com>
* c-common.c (decl_attributes): Issue an error if the argument
to alias is not a string.
Tue Aug 18 13:05:59 BST 1998 Richard Earnshaw (rearnsha@arm.com)
* arm.c (arm_override_options): Remove lie about ignoring PIC flag.
Tue Aug 18 10:32:11 1998 Jeffrey A Law (law@cygnus.com)
* haifa-sched.c (sched_analyze): Put all JUMP_INSNs on the last
pending memory flush list.
* regmove.c (fixup_match_2): Do not call reg_overlap_mentioned_p
on notes.
* regmove.c (optimize_reg_copy_1): Update REG_N_CALLS_CROSSED
and REG_LIVE_LENGTH as successful substitutions are made.
Mon Aug 17 21:07:19 1998 Jeffrey A Law (law@cygnus.com)
* From Graham
* tree.c (build_index_type): Copy TYPE_SIZE_UNIT from sizetype
to itype.
* c-decl.c (finish_enum): Copy TYPE_SIZ_UNIT from enumtype to tem.
* rs6000.c (secondary_reload_class): For TARGET_ELF, indicate that
a BASE_REGS register is needed as an intermediate when copying
a symbolic value into any register class other than BASE_REGS.
Mon Aug 17 11:25:52 1998 Richard Earnshaw <rearnsha@arm.com>
* arm.h (SECONDARY_INPUT_RELOAD_CLASS): Return NO_REGS if compiling
for architecture v4.
