Hal Finkel 2e95afa04c Cleanup stack/frame register define/kill states. This fixes two bugs: 
1. The ST*UX instructions that store and update the stack pointer did not set define/kill on R1. This became a problem when I activated post-RA scheduling (and had incorrectly adjusted the Frames-large test).

2. eliminateFrameIndex did not kill its scavenged temporary register, and this could cause the scavenger to exhaust all available registers (and its emergency spill slot) when there were a lot of CR values to spill. The 2010-02-12-saveCR test has been adjusted to check for this.

autoconf Add support for mipsel in configure. Fixes PR11669. Patch by Sylvestre Ledru. 2011-12-28 17:08:00 +00:00
bindings Update OCaml bindings for the new half float type. 2011-12-28 18:51:08 +00:00
cmake Use 'check_symbol_exists' instead of 'check_function_exists' for finding isatty. This change allows Xcode generated projects to have HAVE_ISATTY to be properly defined. 2011-12-23 01:31:45 +00:00
