Reid Spencer ab926dec56 A very early, rough draft of a guide to making public releases for LLVM. 
This document will detail the steps needed for making a quality release of
LLVM that ensures the release functions and is of high quality.

llvm-svn: 26977
 2006-03-23 06:19:04 +00:00
Reid Spencer 4ef5ad14fa Updated for library changes: 
1. LLVMCBackend.o now depends on LLVMCodeGen.o (why we're not sure)
2. LLVMExecutionEngine.o no longer depends on LLVMInterpreter.o nor LLVMJIT.o
Thanks, Chris.

llvm-svn: 26965
 2006-03-22 22:20:49 +00:00

llvm-svn: 26957
 2006-03-22 19:22:18 +00:00
Evan Cheng d4e1557941 - Supposely movlhps is faster / better than unpcklpd. 
- Don't forget pshufd is only available with sse2.

 2006-03-22 19:12:46 +00:00
Evan Cheng 68ad48bd1a - Implement X86ISelLowering::isShuffleMaskLegal(). We currently only support 
splat and PSHUFD cases.
- Clean up shuffle / splat matching code.

Chris Lattner 7d80b4f366 silence a bogus gcc warning 
llvm-svn: 26953
 2006-03-22 17:27:24 +00:00
Reid Spencer 6f682b79af These changes are necessary to support the new llvm-config tool. llvm-config 
is a handy tool for users of LLVM who want to be able to quickly get
information about LLVM's configuration. It is intended to be used in the
command line of other tools. Documentation will be forthcoming in a
subsequent patch.

llvm-svn: 26952
 2006-03-22 15:59:55 +00:00
Evan Cheng 8fdbdf20cd - VECTOR_SHUFFLE of v4i32 / v4f32 with undef second vector always matches 
PSHUFD. We can make permutes entries which point to the undef pointing
  anything we want.
- Change some names to appease Chris.

llvm-svn: 26949
 2006-03-22 07:10:28 +00:00
Chris Lattner 2d52c1b8b9 Eliminate the dependency of ExecutionEngine on the JIT/Interpreter libraries. 
Now you can build a tool with just the JIT or just the interpreter.

Chris Lattner d3a3365904 wrap lines to 80 columns. 
Add static JITCtor/InterpCtor fields

llvm-svn: 26945
 2006-03-22 06:06:37 +00:00
Chris Lattner eccf46950c This has been implemented. Tweak it into another note 
llvm-svn: 26944
 2006-03-22 05:33:23 +00:00
Chris Lattner 4a66d69433 When possible, custom lower 32-bit SINT_TO_FP to this: 
_foo2:
        extsw r2, r3
        std r2, -8(r1)
        lfd f0, -8(r1)
        fcfid f0, f0
        frsp f1, f0
        blr

instead of this:

_foo2:
        lis r2, ha16(LCPI2_0)
        lis r4, 17200
        xoris r3, r3, 32768
        stw r3, -4(r1)
        stw r4, -8(r1)
        lfs f0, lo16(LCPI2_0)(r2)
        lfd f1, -8(r1)
        fsub f0, f1, f0
        frsp f1, f0
        blr

This speeds up Misc/pi from 2.44s->2.09s with LLC and from 3.01->2.18s
with llcbeta (16.7% and 38.1% respectively).

 2006-03-22 05:30:33 +00:00
Chris Lattner 77373d1bea Add support for "ri" addressing modes where the immediate is a 14-bit field 
which is shifted left two bits before use.  Instructions like STD use this
addressing mode.
