(simplify_relation_operation): We can compute the result of a comparison of CONST_INTs no matter what mode the computation is to be done in. From-SVN: r3372
1993-01-26(simplify_binary_operation, case SMAX): Correctly compute largestRichard Kenner1-1/+1
possible signed integer. From-SVN: r3360
1993-01-12* cse.c (fold_rtx): Call itself with missing arg INSN as NULL_RTX.Brendan Kehoe1-1/+2
From-SVN: r3214
1992-12-08(max_uid): New variable.Richard Kenner1-6/+12
(cse_end_of_basic_block): Use it to ignore insns made by CSE. (cse_main): Set it. From-SVN: r2846
1992-12-04(cse_insn): Always pass result of canon_reg through validate_changeRichard Kenner1-6/+21
before using it in insn. From-SVN: r2835
1992-10-18(canon_reg): Don't call validate_change if INSN is zero.Richard Stallman1-2/+3
From-SVN: r2511
1992-10-15(cse_insn): Add missing call to apply_change_group.Richard Kenner1-0/+1
From-SVN: r2481
1992-10-14(simplify_binary_operation): Insure that folded >> extendsRichard Stallman1-0/+6
the sign even if the host bootstrap compiler doesn't. From-SVN: r2446
1992-10-08(PATHLENGH): Change from 20 to 10 to speed up compilations.Richard Kenner1-1/+1
From-SVN: r2367
1992-09-23(simplify_unary_operation, case SIGN_EXTEND): Use HOST_BITS_PER_WIDE_INT,Richard Kenner1-1/+1
not HOST_BITS_PER_INT. From-SVN: r2219
1992-09-21(find_comparison_args): New args PMODE1, PMODE2.Richard Stallman1-22/+29
(fold_rtx, record_jump_equiv): Use them to get modes of comparison. (fold_rtx): Associate MINUS with nested PLUS. From-SVN: r2197
1992-09-19(fold_rtx): For SUBREG, actually test subreg_lowpart_p in the code to handle ↵Richard Stallman1-1/+8
narrowing subregs. (fold_rtx): For SUBREG, actually test subreg_lowpart_p in the code to handle narrowing subregs. And exclude binary ops like DIV where truncating the args is not valid. From-SVN: r2160
1992-09-07(simplify_binary_operation): For DIV by 0, do nothing.Richard Stallman1-1/+1
From-SVN: r2066
1992-08-19(find_comparison_args): Look for comparison operations if the second arg is ↵Richard Kenner1-3/+7
0 in any mode. (find_comparison_args): Look for comparison operations if the second arg is 0 in any mode. (record_jump_cond): Don't make classes equivalent for floating-point equality comparison. From-SVN: r1900
1992-08-14(fold_rtx): Fix typo in two FLOAT_STORE_FLAG_VALUE tests.Richard Kenner1-2/+2
From-SVN: r1837
1992-08-14(simplify_unary_operation): Remove "else".Richard Kenner1-2/+2
From-SVN: r1828
1992-08-14Fix spelling errors in comments.Torbjorn Granlund1-1/+1
From-SVN: r1825
1992-08-02(canon_hash): Use HOST_WIDE_INT instead of int when casting pointersRichard Kenner1-4/+4
to integers. From-SVN: r1750
