| 4 | default on linux64 again. |
| 5 | * config/sparc/t-linux64: Add mno-app-regs and non-medlow code |
| 6 | models for multilibing. |
| 7 | * genmultilib: Accept | as alternative separator within a set in |

23 | * config/sparc/sparc.h (SPARC_SETHI_P): Don't look at topmost 32 bits |
| 24 | if TARGET_ARCH32. |
| 25 | |
| 3e2a98da |
26 | * longlong.h: Merge in changes from glibc. |
| 27 | Also don't clobber %g2 register in 32bit SPARC assembly, so that |
| 28 | -mno-app-regs libgcc can be compiled. |
| 29 | * libgcc2.c: Add defines so that the updated longlong.h |
| 30 | can be used in libgcc2.a. Also, make sure on most architectures |
| 31 | (at least on all which have optimized code in longlong.h defined |
| 32 | for) {SI,W}_TYPE_SIZE is suitable for preprocessor tests. |

| 35 | |
| 36 | * config/sparc/sol2-64.h: Same as sol2-sld-64.h, except that |

| 38 | * configure.in: Use sol2-64.h instead of sol2-sld-64.h if linker |
| 39 | is GNU ld. |
| 40 | * configure: Rebuilt. |

| 48 | |
| 49 | * Makefile.in (FPBIT_FUNCS, DPBIT_FUNCS): Add _sf_to_usi |
| 50 | _df_to_usi. Required by some targets, so US_SOFTWARE_GOFAST calls to |
| 51 | functions like dptoul will be resolved. |
| 52 | (libgcc2.a): Make sure that the object files from DPBIT are named |
| 53 | differently (prefix `_dp') from those that would be coming from |
| 54 | FPBIT. |

56 | 1999-12-08 Alexandre Oliva <oliva@lsd.ic.unicamp.br>, Jakub Jelinek <jakub@redhat.com> |
| 57 | |
| 58 | * configure.in: When target is sparc* and tm_file contains 64, |
| 59 | test for 64bit support in assembler. If not supported, remove |
| 60 | sparc/t-sol2-64 from target-dependent Makefile fragments. |
| 61 | (AS_SPARC64_FLAG): Define to the assembler flag for 64bit. |
| 62 | (HAVE_AS_OFFSETABLE_LO10): Rework test to use these flags. |
| 63 | (HAVE_AS_REGISTER_PSEUDO_OP): Use config.cache. |
| 64 | * acconfig.h (AS_SPARC64_FLAG): Added. |
| 65 | * configure, config.in: Rebuilt. |
| 66 | * config/sparc/sol2-sld-64.h: Same as sol2.h, if without 64bit |
| 67 | support. Use AS_SPARC64_FLAG. |

| 70 | |
| 71 | * config/sparc/sparc.c (hard_32bit_mode_classes): Mark registers |
| 72 | suitable for holding OFmode values so that gcc works with complex |
| 73 | quad long doubles. |
| 74 | (hard_64bit_mode_classes): Likewise. |
| 75 | |
| 1458fd84 |
76 | * config/sparc/sparc.md (sethi_di_medlow_embmedany_pic): Fix pattern |
| 77 | so that it is actually matched. |
| 78 | (sethi_di_medlow): Likewise. |
| 79 | |
| a5c6cf42 |
80 | * config/sparc/sparc.h (LEGITIMATE_CONSTANT_P): Consider TFmode 0.0L |
| 81 | as legitimate constant if -mvis. |
| 82 | * config/sparc/sparc.md (movtf): Likewise. |
| 83 | (clear_sf): Use const_double_operand. |
| 84 | (clear_sfp, clear_dfp, clear_tf, clear_tfp): New patterns. |
| 85 | |
| 75997b31 |
86 | * config/sparc/sparc.c (sparc_emit_float_lib_cmp): New function. |
| 87 | * config/sparc/sparc-protos.h (sparc_emit_float_lib_cmp): Prototype. |
| 88 | * config/sparc/sparc.h (*_LIBCALL): Only use for _Q_* |
| 89 | routines, _Qp_* cannot be handled like that now. |
| 90 | (INIT_TARGET_OPTABS): Likewise. |
| 91 | * config/sparc/sparc.md (cmptf): Accept soft float ARCH64. |
| 92 | (seq, sne, sgt, sge, slt, sle, beq, bne, bgt, bge, blt, ble): Call |
| 93 | sparc_emit_float_lib_cmp if ARCH64 and soft float. |
| 94 | (extendsftf2, extenddftf2, trunctfsf2, trunctfdf2, floatsitf2, |
| 95 | floatditf2, fix_trunctfsi2, fix_trunctfdi2, addtf3, subtf3, multf3, |
| 96 | divtf3, sqrttf3): New expanders. |
| 97 | (extendsftf2_hq, extenddftf2_hq, trunctfsf2_hq, trunctfdf2_hq, |

| 103 | * configure: Rebuilt. |
| 104 | * config/sparc/linux64.h: Default to -mcpu=ultrasparc if no |
| 105 | -mcpu is given and we're doing 64bit compiles. |

| 108 | |
| 109 | * loop.h (struct induction): Add multi_insn_incr. |
| 110 | * loop.c (basic_induction_var): New multi_insn_incr argument. |
| 111 | Set it if we search back through previous insns for the biv. |
| 112 | (record_biv): New multi_insn_incr argument; fill in struct induction. |
| 113 | (strength_reduce): Discard an iv with multiple bivs, any of |
| 114 | which require multiple insns to increment. |
