| 2011-01-24 | rx: Uncomplicate fp comparisons. | Richard Henderson | 1 | -156/+13 | |
| It turns out that the middle-end will happily take care of doing the swapping and splitting of compound fp comparisons. No need for us to replicate that here. From-SVN: r169169 | |||||
| 2011-01-22 | rx.md (cstoresf4): Pass comparison operator to rx_split_fp_compare. | Nick Clifton | 1 | -1/+1 | |
| * config/rx/rx.md (cstoresf4): Pass comparison operator to rx_split_fp_compare. From-SVN: r169129 | |||||
| 2011-01-22 | rx.md (UNSPEC_CONST): New. | Nick Clifton | 1 | -9/+36 | |
| * config/rx/rx.md (UNSPEC_CONST): New. (deallocate_and_return): Wrap the amount popped off the stack in an UNSPEC_CONST in order to stop it being rejected by -mmax-constant-size. (pop_and_return): Add a "(return)" rtx. (call): Drop the immediate operand. (call_internal): Likewise. (call_value): Likewise. (call_value_internal): Likewise. (sibcall_internal): Likewise. (sibcall_value_internal): Likewise. (sibcall): Likewise. Generate an explicit call using sibcall_internal. (sibcall_value): Likewise. (mov<>): FAIL if a constant operand is not legitimate.

| 2011-01-17 | rx: Split adddi3 and subdi3 after reload. | Richard Henderson | 1 | -17/+199 | |
| The formulation of the pre-reload pattern allows the lower_subreg pass to properly split the patterns. This also required re-writing rx_source_operand and related predicates to accept subregs. From-SVN: r168929 | |||||
| 2011-01-17 | rx: Replace sat builtin with ssaddsi3 pattern. | Richard Henderson | 1 | -10/+31 | |
| A standalone __builtin_rx_sat isn't implementable due to needing to keep the flags live before reload. Instead provide a saturating add pattern, which hopefully will be pattern-matched by high-level optimizations. From-SVN: r168928 | |||||
| 2011-01-17 | rx: Rewrite the bit manipulation patterns. | Richard Henderson | 1 | -45/+162 | |
| The patterns represented with ashift 1 canonically need to have the ashift as the first operand of the logical operation. Leave insv represented as a zero_extract store. Implement a variable store to a 1 bit field as tst+bmne. Implement a variable store of a condition into a 1 bit field with bmcc. From-SVN: r168927 | |||||
| 2011-01-17 | rx: Fix incorrect usage of + in output operands. | Richard Henderson | 1 | -5/+5 | |
| From-SVN: r168926 | |||||
| 2011-01-17 | rx: Cleanup non-VOIDmode SETs. | Richard Henderson | 1 | -188/+70 | |
| SET should always have VOIDmode. A number of places used SImode or QImode for the mode of the SET rtx itself. From-SVN: r168925 | |||||
| 2011-01-17 | rx: Cleanup flags generation. | Richard Henderson | 1 | -69/+237 | |
| All arithmetic should only clobber the flags by default; setting the flags to a useful value should be done by a separate pattern. From-SVN: r168924 | |||||

| 2011-01-17 | rx: Split cstoresi4 post-reload. | Richard Henderson | 1 | -12/+29 | |
| This will allow elimination of the compare. From-SVN: r168920 | |||||
| 2011-01-17 | rx: Cleanup conditional branches. | Richard Henderson | 1 | -202/+179 | |
| Use match_operator, not code_iterators. Use a new helper function, rx_split_cbranch. Get the modes right on the comparisons. Distinguish fp comparisons with CC_Fmode. From-SVN: r168919 | |||||
| 2011-01-17 | rx: Remove rx_compare_redundant. | Richard Henderson | 1 | -6/+1 | |
| To be replaced by the generic compare_elim pass, but we need to disable this before fiddling with the arrangement of the arithmetic instructions, as required by the generic pass. From-SVN: r168916 | |||||
