| Store inc into fp->inc so that record_control_macro doesn't |
| need to do a table lookup. |

| (movstrsi): Remove match_operand predicates, since |
| expand_block_move does the checking. |
| (sync_isync): Delete. |
| (icbi, dcbst, sync, isync): New insns to generate named instruction |
| for making trampolines on eabi/V.4 properly flush the caches. |
| (decrement_and_branch_on_count): Rename from |
| decrement_and_branchsi. Add update of count in insn pattern. |
| |
| * rs6000/sysv4.h (TARGET_SWITCHES): Drop -mtraceback. Keep |
| -mno-traceback but don't do anything with it. Add |
| -mcalls-{nt,aixdesc}. Add -m{,no-}relocatable-lib. Add -msim, |
| -mmvme, and -memb. |
| (TARGET_TOC): Update for use with -mcalls-{nt,aixdesc}. |
| (SUBTARGET_OVERRIDE_OPTIONS): Update for new switches. |
| (RS6000_OUTPUT_BASENAME): Delete. |
| (toc_section): Add support for -mcall-{nt,aixdesc}. |
| (ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): Ditto. |
| (ASM_DECLARE_FUNCTION_NAME): Use STRIP_NAME_ENCODING instead of |
| RS6000_OUTPUT_BASENAME. For -mcall-{nt,aixdesc} emit the proper |
| function descriptor. |
| (ASM_SPEC): Pass appropriate -mxxx switches to the assembler based |
| on the -mcpu=xxx options. |
| (ASM_OUTPUT_INT): Move here from eabi.h. |
| (ENCODE_SECTION_INFO): If -mcall-{nt,aixdesc} add appropriate magic |
| so function name has two or one leading periods. |
| (ASM_OUTPUT_SOURCE_LINE): Delete, use version in svr4.h. |
| (trampoline macros): Call trampoline functions in rs6000.c. |
| |
| * t-{eabi,ppc}{,gas} (EXTRA_HEADERS): Add ginclude/ppc-asm.h. |
| (LIB2FUNCS_EXTRA): Depend on eabi.S, not eabi.s. |
| (eabi.S): Rename from eabi.asm. |
| |
| * t-{eabi,ppc}gas (MULTILIB_*): Add -mcall-aixdesc libraries, but |
| don't build either little endian or -mrelocatable versions of |
| those libraries. |

| * rs6000.md (divsi3): Reorder so common mode does not negate |
| power-of-2 shift optimization. |

| |
| * configure (sparc-*-solaris2*): Add gcrt1.o to extra_parts. |
| * sparc/sol2.h (STARTFILE_SPEC): Link with gcrt1.o with -pg. |
| * sparc/sol2-g1.asm: New file, startup code for profiled |
| executables. |
| * sparc/t-sol2: Add make rule for gcrt1.o. |
| * sparc/gmon-sol2.c (_mcleanup): Add support for PROFDIR |
| environment variable. |

| * mips/abi64.h (CPP_SPEC): If -msingle-float and not |
| -msoft-float, pass -D__mips_single_float. Likewise for -m4650 and |
| not -msoft-float. |
| * mips/dec-bsd.h (CPP_SPEC): Likewise. |
| * mips/dec-osf1.h (CPP_SPEC): Likewise. |
| * mips/elf64.h (CPP_SPEC): Likewise. |

| * mips/osfrose.h (CPP_SPEC): Likewise. |
| * mips/t-ecoff (MULTILIB_OPTIONS, MULTILIB_DIRNAMES, |
| MULTILIB_MATCHES): Add -msingle-float support. |

| |
| * toplev.c (main): Invoke OPTIMIZATION_OPTIONS after target_flags |
| has been initialized so sets of target_flags aren't clobbered. |
| |
| * cccp.c (do_include): Recognize c:\foo as absolute path name in DOS. |
| |
| * svr4.h (MD_EXEC_PREFIX): Don't use if cross compiling. |
| (MD_STARTFILE_PREFIX): Likewise. |
| (LINK_SPEC): Don't use absolute path names if cross compiling. |
