Chris Lattner 6d87faf14f new testcase 
llvm-svn: 35927
 2007-04-11 22:36:10 +00:00
Chris Lattner a5fcd24746 Fix CodeGen/X86/2007-03-24-InlineAsmPModifier.ll 
llvm-svn: 35926
 2007-04-11 22:29:46 +00:00
Reid Spencer 45fc9400ad The "Hello" message is written on stderr so make sure it is duplicated to 
stdout so the grep can match it.

llvm-svn: 35925
 2007-04-11 21:30:05 +00:00
Reid Spencer a28d662816 Add Scott's note about GCC 4.1.2 on OpenSUSE. 
llvm-svn: 35924
 2007-04-11 21:28:31 +00:00
Reid Spencer 5f89562811 Add a test case for PR1318. 
llvm-svn: 35923
 2007-04-11 21:14:53 +00:00
Reid Spencer c78d122a6a Build Hello by default so it can be used in test cases. 
llvm-svn: 35922
 2007-04-11 21:03:37 +00:00
Reid Spencer 645d5a9f4f Use the new %link variable to make this test portable. 
llvm-svn: 35921
 2007-04-11 21:00:00 +00:00
Reid Spencer 641527f3e2 Make new variables available: compile_c, compile_cxx, link to handle tests 
that want to use LLVM's notion of compiling and linking programs. This
includes all the -I -L and optimization switches that LLVM would using to
compile or link any of this files.

llvm-svn: 35920
 2007-04-11 20:57:39 +00:00
Reid Spencer 8e25101211 The "implementation" keyword is no more! 
llvm-svn: 35919
 2007-04-11 20:06:03 +00:00
Reid Spencer d029c7e666 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.

llvm-svn: 35918
 2007-04-11 19:56:59 +00:00
Reid Spencer f29754c7b9 Add a test case for testing basic IR features via llvm2cpp. This helps find 
bit rot in llvm2cpp and also tests the LLVM C++ IR in ways that llvm-as
doesn't.

llvm-svn: 35917
 2007-04-11 19:54:37 +00:00
Reid Spencer 669c7e58b0 Make sure upgrade doesn't fail on this. 
llvm-svn: 35916
 2007-04-11 19:36:27 +00:00
Reid Spencer 60012ded54 Update the way llvm2cpp tests are done: 
1. Make sure bytecode/assembly inputs are always redirected stdin so that
   the module name is <stdin>. This helps not get false negatives when the
   diff is done.
2. Scan the test file to determine if llvm-upgrade needs to be run.
3. Avoid running testings that are XFAIL'd because they'll cause a failure
   when run for llvm2cpp.
4. Get some better error message output.

llvm-svn: 35914
 2007-04-11 17:56:23 +00:00
Reid Spencer 7a311b86e1 Upgrade this file completely instead of downgrading it. Make sure that 
false positives aren't made.

llvm-svn: 35904
 2007-04-11 15:24:04 +00:00
Reid Spencer 871a9ea4ef Fix a bug where ICmpInst objects instantiated directly with a name would 
not retain that name. Not noticed because AsmParser always sets name after
construction. However, llvm2cpp noticed.

llvm-svn: 35903
 2007-04-11 13:04:48 +00:00
Reid Spencer 5899dd1dc3 Make the generated code for ConstantInt nicer.

Don't allow false positives.

llvm-svn: 35899
 2007-04-11 12:41:49 +00:00
Reid Spencer ff6e0eda94 Fix several bugs relating to changes in the LLVM IR API or just outright 
typos in the output. This is sufficient to get most of the llvm2cpp tests
working again.

llvm-svn: 35898

Chris Lattner 81f14c63da sext of compares. 
llvm-svn: 35892
 2007-04-11 06:57:54 +00:00
Chris Lattner 74ff60ff84 Turn stuff like: 
icmp slt i32 %X, 0              ; <i1>:0 [#uses=1]
        sext i1 %0 to i32               ; <i32>:1 [#uses=1]

into:

        %X.lobit = ashr i32 %X, 31              ; <i32> [#uses=1]

This implements InstCombine/icmp.ll:test[34]

llvm-svn: 35891
 2007-04-11 06:57:46 +00:00
Chris Lattner d0f7942e23 Simplify some comparisons to arithmetic, this implements:

Chris Lattner 20f2372a7c canonicalize (x <u 2147483648) -> (x >s -1) and (x >u 2147483647) -> (x <s 0) 
llvm-svn: 35886
 2007-04-11 06:12:58 +00:00
Chris Lattner 7ddbff090a fix a miscompilation of: 
define i32 @test(i32 %X) {
entry:
        %Y = and i32 %X, 4              ; <i32> [#uses=1]
        icmp eq i32 %Y, 0               ; <i1>:0 [#uses=1]
        sext i1 %0 to i32               ; <i32>:1 [#uses=1]
        ret i32 %1
}

by moving code out of commonIntCastTransforms into visitZExt.  Simplify the
APInt gymnastics in it etc.

 2007-04-11 05:34:00 +00:00
Chris Lattner 65786b078c Teach the codegen to turn [aez]ext (setcc) -> selectcc of 1/0, which often 
allows other simplifications.  For example, this compiles:
int isnegative(unsigned int X) {
   return !(X < 2147483648U);
}

Into this code:

x86:
        movl 4(%esp), %eax
        shrl $31, %eax
        ret
arm:
        mov r0, r0, lsr #31
        bx lr
thumb:
        lsr r0, r0, #31
        bx lr

instead of:

x86:
        cmpl $0, 4(%esp)
        sets %al
        movzbl %al, %eax
        ret

arm:
        mov r3, #0
        cmp r0, #0
        movlt r3, #1
        mov r0, r3
        bx lr

thumb:
        mov r2, #1
        mov r1, #0
        cmp r0, #0
        blt LBB1_2      @entry
LBB1_1: @entry
        cpy r2, r1
LBB1_2: @entry
        cpy r0, r2
        bx lr

Reid Spencer a472f66dd0 For PR1146: 
Put the parameter attributes in their own ParamAttr name space. Adjust the
rest of llvm as a result.

llvm-svn: 35877
 2007-04-11 02:44:20 +00:00
Reid Spencer d3f622e0d5 Teach sys::Path how to recognize different kinds of object files for ELF 
and Mach-O systems. Additionally, correct the Mach-O logic code to look at
byte 12 not byte 15. Hopefully this fixes the llvm-ld warning on Darwin.

llvm-svn: 35876
 2007-04-11 02:02:09 +00:00
Chris Lattner daa012d1fb Simplify SROA conversion to integer in some ways, make it more general in others. 
We now tolerate small amounts of undefined behavior, better emulating what
would happen if the transaction actually occurred in memory.  This fixes
SingleSource/UnitTests/2007-04-10-BitfieldTest.c on PPC, at least until
Devang gets a chance to fix the CFE from doing undefined things with bitfields :)
