Reid Spencer 91b273ae39 XFAIL this test for now. It will be a while before I can implement this 
intrinsic properly in SDISel.

Chris Lattner 9df6baa772 Add a helper class (APSInt) which can represent an APInt along with sign 
information.  This is useful when a value does have a sign associated with
it.  This shouldn't be used generally in LLVM for mid-level optimizer stuff.

Reid Spencer d1b53f538d For PR1302: 
Use local variable names that match the function parameter name that it
is passed to so the code is more clear, to wit: is_bytecode -> is_native

the file is native. Don't generate warnings if the file is native.

llvm-svn: 35653
 2007-04-04 06:33:17 +00:00
Reid Spencer 031fb8d4dc Make the LinkInFile and LinkInLibrary both return an indication of whether 
the file was found to be a native library (and thus not linked by these
functions).

Nicolas Geoffray 23710a7da3 Starting implementation of the ELF32 ABI specification of varargs handling. 
LowerVASTART emits the right code if the subtarget is ELF32, the other intrinsics
(VAARG, VACOPY and VAEND) are not yet implemented.

llvm-svn: 35625
 2007-04-03 13:59:52 +00:00
Nicolas Geoffray b3e99a18ee The PPC64 ELF ABI is "intended to use the same structure layout and calling convention rules 
as the 64-bit PowerOpen ABI" (Reference http://www.linux-foundation.org/spec/ELF/ppc64/).
Change all ELF tests to ELF32.

Nicolas Geoffray ab559f6e3c Addition to the previous commit for getCalleeSavedRegClasses:

Reid Spencer d0b2dbfa03 Prepare for Subversion migration by implementing a -usesvn to tell the 
script to to check out llvm and llvm-test from Subversion instead of CVS.
Without this option the script will continue to check out from CVS. To
specify the Subversion URL, set the SVNURL environment variable or pass
-svnurl followed by the URL. For now, -svnurl will default to Reid's
temporary (read-only, daily snapshot) SVN server. Try it out if you like!

recent dagcombine patch

llvm-svn: 35606
 2007-04-02 22:08:54 +00:00
Scott Michel 16627a542f 1. Insert custom lowering hooks for ISD::ROTR and ISD::ROTL. 
2. Help DAGCombiner recognize zero/sign/any-extended versions of ROTR and ROTL
patterns. This was motivated by the X86/rotate.ll testcase, which should now
generate code for other platforms (and soon-to-come platforms.) Rewrote code
slightly to make it easier to read.

Chris Lattner 28e0e4e11e Pass the type of the store access, not the type of the store, into the 
target hook.  This allows us to codegen a loop as:

LBB1_1: @cond_next
        mov r2, #0
        str r2, [r0, +r3, lsl #2]
        add r3, r3, #1
        cmn r3, #1
        bne LBB1_1      @cond_next

instead of:

LBB1_1: @cond_next
        mov r2, #0
        str r2, [r0], #+4
        add r3, r3, #1
        cmn r3, #1
        bne LBB1_1      @cond_next

This looks the same, but has one fewer induction variable (and therefore,
one fewer register) live in the loop.

Chris Lattner 3e21eb7fd7 Fix a bug which caused us to never be able to use signed comparisons for 
equality comparisons of a constant.  This allows us to codegen the 'sintzero'

LBB1_1: ;cond_next
        li r4, 0
        addi r2, r2, 1
        stw r4, 0(r3)
        addi r3, r3, 4
        cmpwi cr0, r2, -1
        bne cr0, LBB1_1 ;cond_next

instead of:

LBB1_1: ;cond_next
        addi r2, r2, 1
        li r4, 0
        xoris r5, r2, 65535

Chris Lattner c3748562bd Various passes before isel split edges and do other CFG-restructuring changes. 
isel has its own particular features that it wants in the CFG, in order to
reduce the number of times a constant is computed, etc.  Make sure that we
clean up the CFG before doing any other things for isel.  Doing so can
dramatically reduce the number of split edges and reduce the number of
places that constants get computed.  For example, this shrinks
CodeGen/Generic/phi-immediate-factoring.ll from 44 to 37 instructions on X86,
and from 21 to 17 MBB's in the output.  This is primarily a code size win,
not a performance win.

Reid Spencer eba021453b For PR1297: 
Implement bswap, ctpop, ctlz, and cttz utilizing the new overloaded
intrinsic feature of tblgen. By defining llvm_int_ty to have an ValueType
of iAny, any intrinsic using that type becomes an overloaded intrinsic.
This signals that a) any integer type could be used for that argument and
b) the intrinsic needs a suffix to match each such argument for the
actual intrinsic.

 2007-04-01 07:30:57 +00:00
Reid Spencer c7c4880ab1 For PR1297:

Reid Spencer 2a2117c82d For PR1297: 
Implement "actual" argument types for the Intrinsic member functions. This

the caller knows the actual argument types desired.

Reid Spencer 7c57b88b27 For PR1297: 
1. Clear up confusion between "GotBits" and "ExpectBits". GotBits is the
   type actually provided. ExpectedBits is the type expected for the
   intrinsics. Before this patch, it was reversed!
2. Implement checks for overloaded intrinsics. This involves computing the
   suffix expected and making sure the suffix matches the function name. It
   also includes some intrinsic-specific checks such as ensuring that the
   bswap parameter and result are the same width and an even number of bytes.

llvm-svn: 35540
 2007-04-01 07:22:57 +00:00
Reid Spencer e67d0c226d For PR1297: 
Implement code generation for overloaded intrinsic functions. The basic
difference is that "actual" argument types must be provided when
constructing intrinsic names and types. Also, for recognition, only the
prefix is examined. If it matches, the suffix is assumed to match. The
suffix is checked by the Verifier, however.

 2007-03-29 16:48:16 +00:00
Reid Spencer 0f92f0e519 For PR789: 
* Add a method: bool isAbsolute() const, which determines if the path name
  is absolute or not.
* Implement caching of file status information in the Path object. Allow it
  to be updated forcefully or lazily re-fetched from the cached value.

Reid Spencer 2e35a58838 Replace the "implementation" keyword with "checkpoint". This more accurately 
describes its function as check against unresolved types and definitions.
This is handy for forcing error messages in assembly test cases or otherwise
ensuring that everything is resolved at that point in the assembly.
