Also missing documentation in invoke.texi? Other than that, ok. David On Thu, May 22, 2014 at 5:00 PM, Paul Pluzhnikov wrote: > On Thu, May 22, 2014 at 4:36 PM, Sriraman Tallam wrote: >> This patch is pending review for trunk. Please see if this is ok to >> commit to google/gcc-4_8 branch. Plea

patch to fix PR61215

The following patch fixes https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61215 The patch was bootstrapped on x86/x86-64 and arm and tested on x86/x86-64. Unfortunately I did not managed to decrease the test significantly to include it into the testsuite. Committed as rev. 210828 into

[PATCH 2/9] rs6000: New type attribute value "halfmul"

This is for the legacy integer multiply-accumulate instructions. Quite a mouthful, and "mulhw" is also a terrible name since we already have a machine instruction called exactly that. Hence "halfmul". Also fixes the titan automaton description for this. 2014-05-22 Segher Boessenkool gcc/

[PATCH 1/9] rs6000: Clean up the "type" attribute

Get rid of the one huge line. Group and order things a bit. Further changes will follow so this doesn't try to make it perfect. The rest of this patch series reduces the number of different integer instruction types by folding many together using attributes "size" (the data size), "dot" (does th

[PATCH 3/9] rs6000: Make all multiply instructions one type

This uses the attributes "size" and "dot" to specify the differences: imul3 -> mul size=8 imul2 -> mul size=16 imul -> mul size=32 lmul -> mul size=64 imul_compare -> mul size=32 dot=yes lmul_compare -> mul size=64 dot=yes 2014-05-22 Segher Boesse

[PATCH 4/9] rs6000: Make all insert instructions one type

This uses the attribute "size" to specify the differences: insert_word -> insert size=32 insert_dword -> insert size=64 It could use "dot" as well, but the current code doesn't handle that. 2014-05-22 Segher Boessenkool gcc/ * config/rs6000/rs6000.md (type): Delete

[PATCH 9/9] rs6000: Make all rlw*nm and rld*c* type shift

They are often labeled just "integer" currently. Fix that. Also handle shift properly in those scheduling descriptions that neglected it. 2014-05-22 Segher Boessenkool gcc/ * config/rs6000/440.md (ppc440-integer): Include shift without dot. (ppc440-compare): Include

[PATCH 7/9] rs6000: Make all add instructions one type

They are currently just "integer", but the dot version is fast_compare. This makes them all "add". Later we should introduce attributes to distinguish e.g. addc and adde (which aren't currently handled as separate instructions at all, only in groups). 2014-05-22 Segher Boessenkool gcc/
