Evan Cheng d8771e915c New test case. 
llvm-svn: 42963
 2007-10-14 10:15:03 +00:00
Evan Cheng cdf3609130 Revert 42908 for now. 
llvm-svn: 42960
 2007-10-14 05:57:21 +00:00
Evan Cheng f86204baf4 Fix test case. 
llvm-svn: 42949
 2007-10-13 03:14:06 +00:00
Evan Cheng 54bec86754 New tests. 
llvm-svn: 42948
 2007-10-13 03:10:54 +00:00
Dan Gohman e0ad9ea7cd Fix this test to not depend on the assembly output containing something 
that includes the string "st". This probably fixes the regression on
Darwin.

 2007-10-12 20:42:14 +00:00
Dan Gohman dc35bd79ca Change the names used for internal labels to use the current 
function symbol name instead of a codegen-assigned function
number.

Thanks Evan! :-)

Evan Cheng b83a379f4f EXTRACT_SUBREG test case. 
llvm-svn: 42900
 2007-10-12 09:03:31 +00:00
Arnold Schwaighofer 9653e677d5 Added missing -march=x86 flag. 
llvm-svn: 42893
 2007-10-12 07:49:48 +00:00
Dan Gohman be37007e64 Add intrinsics for sin, cos, and pow. These use llvm_anyfloat_ty, and so 
may be overloaded with vector types. And add a testcase for codegen for
these.

llvm-svn: 42885
 2007-10-12 00:01:22 +00:00
Dan Gohman 3554448947 Add an explicit target triple to make this test behave as expected on 
non-Apple hosts. And use the count script instead of wc + grep.

llvm-svn: 42878
 2007-10-11 23:04:36 +00:00
Arnold Schwaighofer 9ccea99165 Added tail call optimization to the x86 back end. It can be 
enabled by passing -tailcallopt to llc.  The optimization is
performed if the following conditions are satisfied:
* caller/callee are fastcc
* elf/pic is disabled OR
  elf/pic enabled + callee is in module + callee has
  visibility protected or hidden

Dan Gohman 678387a299 These two tests now require only two multiply instructions, 
instead of four.

llvm-svn: 42784

Evan Cheng 3b3e6097a3 Update test. 
llvm-svn: 42775
 2007-10-08 22:20:32 +00:00
Dan Gohman a24b431b27 These two tests now require only three multiply instructions, 
instead of four.

Dale Johannesen bcfa7c1255 Make test work on non-x86 hosts. 
llvm-svn: 42671
 2007-10-06 01:22:39 +00:00
Evan Cheng 5ee9cf6bca Test case for 3-address conversion. 
llvm-svn: 42664
 2007-10-05 23:33:09 +00:00
Evan Cheng 484cab7a2f Enable convertToThreeAddress for X86 by default. 
llvm-svn: 42655

Dan Gohman a90183e7d1 Teach SplitVectorOp how to split INSERT_VECTOR_ELT.

 2007-09-28 23:53:40 +00:00
Rafael Espindola 6c04ac1db0 Refactor the memcpy lowering for the x86 target. 
The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

llvm-svn: 42433
 2007-09-28 12:53:01 +00:00
Dale Johannesen 25a00a63eb Add sqrt and powi intrinsics for long double. 
llvm-svn: 42423
 2007-09-28 01:08:20 +00:00
Dale Johannesen b805d35d16 Modernize fabs.ll, add long double. Add tests 
for direct codegen of fsin/fcos.

 2007-09-26 21:12:10 +00:00
Dan Gohman 31599685c7 When both x/y and x%y are needed (x and y both scalar integer), compute 
both results with a single div or idiv instruction. This uses new X86ISD
nodes for DIV and IDIV which are introduced during the legalize phase
so that the SelectionDAG's CSE can automatically eliminate redundant
computations.

llvm-svn: 42308
 2007-09-25 18:23:27 +00:00
Dale Johannesen 97d4bf2c41 Some tests for APFloat conversions. 
llvm-svn: 42303
 2007-09-25 17:50:55 +00:00
Evan Cheng 6cb71f7fe0 Forgot to check in the changes. Fix test case so it doesn't break with any scheduling changes. 
llvm-svn: 42302
 2007-09-25 17:47:38 +00:00
Dan Gohman 6002818999 Use the correct result value type instead of using getValueType(0) 
in ExpandEXTRACT_VECTOR_ELT and SplitVectorOp. This fixes an abort
in the included testcase.

llvm-svn: 42264
 2007-09-24 15:54:53 +00:00
Dale Johannesen ae4bb05103 Implementation of +sse -sse2 has changed; add 
-sse to preserve intent of this test.

 2007-09-23 14:58:14 +00:00
Rafael Espindola 4730c04904 Don't add a default STACK_ALIGN (use the generic ABI alignment) 
Implement calls to functions with byval arguments on X86

llvm-svn: 42192
 2007-09-21 15:50:22 +00:00
Dan Gohman 4dbc582a36 Fix several more entries in the x86 reload/remat folding tables. 
llvm-svn: 42162
 2007-09-20 14:17:21 +00:00
Evan Cheng e7ff9da64b Clean up. 
llvm-svn: 42112
 2007-09-18 22:56:31 +00:00
Evan Cheng e2e8f2d96b Fix a bogus splat xform: 
shuffle <undef, undef, x, undef>, <undef, undef, undef, undef>, <2, 2, 2, 2>
!=
<undef, undef, x, undef>

Bill Wendling 067f1d8e95 Objective-C was generating EH frame info like this: 
"_-[NSString(local) isNullOrNil]".eh = 0
        .no_dead_strip  "_-[NSString(local) isNullOrNil]".eh

The ".eh" should be inside the quotes.

llvm-svn: 42074
 2007-09-18 01:47:22 +00:00
Dan Gohman 863bdc332d Emit integer x<1 as x<=0, as comparisons with zero (now includeing 
64-bit) can use test instead of cmp with an immediate.

llvm-svn: 42026
 2007-09-17 14:49:27 +00:00
Dan Gohman 51d1929b9e Use "test reg,reg" in place of "cmp reg,0" for 64-bit operands. This was 
previously only done for 32-bit and smaller operands.

Rafael Espindola 272f7304f0 Add support for functions with byval arguments on x86 
llvm-svn: 41953
 2007-09-14 15:48:13 +00:00
Dan Gohman a95cbb0007 Avoid storing and reloading zeros and other constants from stack slots 
by flagging the associated instructions as being trivially rematerializable.

llvm-svn: 41775
 2007-09-07 21:32:51 +00:00
Rafael Espindola 1de0c86717 Add support for having different alignment for objects on call frames. 
The x86-64 ABI states that objects passed on the stack have
8 byte alignment. Implement that.

llvm-svn: 41768
 2007-09-07 14:52:14 +00:00
Anton Korobeynikov 122bf4be7e Split eh.select / eh.typeid.for intrinsics into i32/i64 versions. This is needed, because they just "mark" register 
liveins and we let frontend solve type issue, not lowering code :)

llvm-svn: 41763
 2007-09-07 11:39:35 +00:00
Anton Korobeynikov a07765b8f4 Proper handle case, when aliasee is external weak symbol referenced only by alias itself. 
Also, fix a case, when target doesn't have weak symbols supported.

llvm-svn: 41746
 2007-09-06 17:21:48 +00:00
Evan Cheng 189df733ed Fix a bug in X86InstrInfo::convertToThreeAddress that caused it to codegen: 
leal    (,%rcx,8), %rcx
It should be
leal    (,%rcx,8), %ecx

llvm-svn: 41735
 2007-09-06 00:14:41 +00:00
Dale Johannesen 6480cc6f8c Change all floating constants that are not exactly 
representable to use hex format.

llvm-svn: 41722
 2007-09-05 17:50:36 +00:00
Evan Cheng e0cb6bb8da Fix for PR1632. EHSELECTION always produces a i32 value. 
llvm-svn: 41712
 2007-09-04 20:39:26 +00:00
Rafael Espindola e636fc05d6 Initial support for calling functions with byval arguments on x86-64 
llvm-svn: 41643
 2007-08-31 15:06:30 +00:00
Evan Cheng 2e9d48aa0d Update test case to reflect Dale's change. 
llvm-svn: 41639

Tanya Lattner ffb806cf0e Do not run on darwin. 
llvm-svn: 41608
 2007-08-30 16:07:20 +00:00
Evan Cheng ebb8540067 Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses. 
llvm-svn: 41599
 2007-08-30 05:54:07 +00:00
Dan Gohman 312b70a970 Add explicit triples to avoid default behavior that varies by host. 
llvm-svn: 41510
 2007-08-27 20:54:48 +00:00
Dan Gohman 8dc0b93151 If the source and destination pointers in an llvm.memmove are known 
to not alias each other, it can be translated as an llvm.memcpy.
