* FastISel support for i1 constants.Dan Gohman2008-09-101-2/+10
| | | | llvm-svn: 56068
* Fix a bug in the coalescer where it didn't check if a live interval existed ↵Owen Anderson2008-09-101-1/+1
| | | | | | | | before trying to manipulate it. This was exposed by fast isel's handling of shifts on X86-64. With this, FreeBench/pcompress2 passes on X86-64 in fast isel. llvm-svn: 56067
* Add X86FastISel support for static allocas, and refencesDan Gohman2008-09-102-14/+23
| | | | | | | to static allocas. As part of this change, refactor the address mode code for laods and stores. llvm-svn: 56066
* Fix PR2664 - spiller GetRegForReload wasn't respecting sub-register indices ↵Evan Cheng2008-09-101-2/+4
| | | | | | on machine operands. llvm-svn: 56065
* Add a break statement that I accidentally deleted whenDan Gohman2008-09-101-0/+1
| | | | | | | I shuffled the fast-isel command-line options around. This fixes a bunch of fast-isel failures. llvm-svn: 56057
* Remove unnecessary bit-wise AND from the limited precision work.Bill Wendling2008-09-101-6/+4
| | | | llvm-svn: 56049
* Fix 80 col violation.Daniel Dunbar2008-09-101-1/+2

* Fix typo.Evan Cheng2008-09-101-2/+2
| | | | llvm-svn: 56037
* Check that both operands are f32 before attempting to lower.Bill Wendling2008-09-101-0/+1
| | | | llvm-svn: 56036
* Implement "visitPow". This is mainly used to see if we have a pow() call of thisBill Wendling2008-09-102-4/+146
| | | | | | | | | | | form: powf(10.0f, x); If this is the case, and also we want limited precision floating-point calculations, then lower to do the limited-precision stuff. llvm-svn: 56035
* A few more places where FPOW is being ignored.Evan Cheng2008-09-091-7/+13
| | | | llvm-svn: 56032
* Change -fast-isel-no-abort to -fast-isel-abort, which now defaultsDan Gohman2008-09-091-7/+12
| | | | | | | | to being off by default. Also, add assertion checks to check that the various fast-isel-related command-line options are only used when -fast-isel itself is enabled. llvm-svn: 56029
* Legalizer was missing code that expand fpow to a libcall.Evan Cheng2008-09-091-10/+12
| | | | llvm-svn: 56028
* Adding 6-, 12-, and 18-bit limited-precision floating-point support for exp2Bill Wendling2008-09-091-26/+111

* Move the uglier parts of deciding not to emit aDale Johannesen2008-09-091-15/+4
| | | | | | | | | UsedDirective for some symbols in llvm.used into Darwin-specific code. I've decided LessPrivateGlobal is potentially a useful abstraction and left it in the target-independent area, with improved comment. llvm-svn: 56024
* Add support for 6-, 12-, and 18-bit limited precision calculations of exp forBill Wendling2008-09-091-7/+134
| | | | | | floating-point numbers. llvm-svn: 56023
* Add a new option, -fast-isel-verbose, that can be used withDan Gohman2008-09-091-15/+21
| | | | | | | -fast-isel-no-abort to get a dump of all unhandled instructions, without an abort. llvm-svn: 56021
* Clear preference when it no longer makes sense.Evan Cheng2008-09-091-0/+8
| | | | llvm-svn: 56019
* Clean this up, based on Evan's suggestions.Owen Anderson2008-09-091-2/+2
| | | | llvm-svn: 56009
* - Add support for 6-, 12-, and 18-bit limited precision floating-point "log"Bill Wendling2008-09-091-112/+216
| | | | | | | values. - Refactored some of the code. llvm-svn: 56008
* Fix PR2757. Ignore liveinterval register allocation preference if the ↵Evan Cheng2008-09-091-1/+1
| | | | | | preference register is not in the right register class. This can happen due to sub-register coalescing. llvm-svn: 56006
* Make safer variant of alias resolution routine to be defaultAnton Korobeynikov2008-09-091-1/+1
| | | | llvm-svn: 56005
* Add limited precision floating-point conversions of log10 for 6- and 18-bitBill Wendling2008-09-091-4/+55
| | | | | | precisions. llvm-svn: 56000
* Check for type legality before materializing integer constants in fast isel. ↵Owen Anderson2008-09-091-0/+2
| | | | | | | | With this change, all of MultiSource/Applications passes on Darwin/X86 under FastISel. llvm-svn: 55982
* Remove the code that protected FastISel from aborting inDan Gohman2008-09-091-5/+2
| | | | | | | | the case of loads, stores, and conditional branches. It can handle those now, so any that aren't handled should trigger the abort. llvm-svn: 55977
* Fix a constant lowering bug. Now we can do load and store instructions with ↵Evan Cheng2008-09-091-0/+13
| | | | | | funky getelementptr embedded in the address operand. llvm-svn: 55975
* Fix logic for not emitting no-dead-strip for someDale Johannesen2008-09-091-2/+14
| | | | | | | | | | objects in llvm.used (thanks Anton). Makes visible the magic 'l' prefix for symbols on Darwin which are to be passed through the assembler, then removed at linktime (previously all references to this had been hidden in the ObjC FE code, oh well). llvm-svn: 55973
* Add support for floating-point calculations of log2 with limited precisions of 6Bill Wendling2008-09-091-76/+191

* Don't suppress no-dead-strip for used static functions.Dale Johannesen2008-09-081-1/+1

* Revert my previous change -- the subtraction of two constants was a no-opBill Wendling2008-09-081-1/+1
| | | | | | | | | before. This is taken care of in the selection DAG pass. In my opinion, this should be in one place or the other. I.e., it should probably be removed from the DAG combiner (along with the other arithmetic transformations on constants that are essentially no-ops). llvm-svn: 55889
