Bill Wendling 6869b6abf8 Simplification noticed by Chris. 
llvm-svn: 130864
 2011-05-04 20:28:12 +00:00
Bill Wendling 5f9150b5b1 Convert the non-temporal store builtins to LLVM-native IR.

Fariborz Jahanian 24ac1599fc Generalize case for built-in expressions having 
side-effect to generate their ir. Not just for
__builtin_expect. // rdar://9330105

llvm-svn: 130172
 2011-04-25 23:10:07 +00:00
Fariborz Jahanian 5a866c0bf2 Ir-gen the side-effect(s) when __builtin_expect is 
constant-folded. // rdar://9330105

llvm-svn: 130163

Chris Lattner 54fd1a1ad3 fix a crash on code that uses the result value of __builtin___memcpy_chk. 
llvm-svn: 129892
 2011-04-20 23:14:50 +00:00
Chris Lattner 30107ed600 fold memcpy/set/move_chk to llvm.memcpy/set/move when the sizes 
are trivial.  This exposes opportunities earlier, and allows fastisel
to do good things with these at -O0.

This addresses rdar://9289468 - clang doesn't fold memset_chk at -O0

Bill Wendling a865185ad6 Removing the unaligned load tests from builtins-x86.c since they're generated by a regular 'load' now. 
llvm-svn: 129464
 2011-04-13 20:17:22 +00:00
Bill Wendling 88ae43772a It looks like the FreeBSD buildbot needs this for the builtins-x86.c test.

 2011-04-13 10:02:54 +00:00
Bill Wendling b9c9e34cb3 Just use a native "load" instead of translating the builtin later. Clang can 
take it!

I wasn't able to get __builtin_ia32_loaddqu to transform into an unaligned
load...I'll have to look into it further.

llvm-svn: 129427
 2011-04-13 05:58:17 +00:00
Bill Wendling 3137d3cb49 Convert the unaligned load builtins to the first-class versions.

Chris Lattner 9cb59fa834 add a __sync_swap builtin to fill out the rest of the __sync builtins.

Jay Foad 20c0f02cc5 Remove PHINode::reserveOperandSpace(). Instead, add a parameter to 
PHINode::Create() giving the (known or expected) number of operands.

llvm-svn: 128538
 2011-03-30 11:28:58 +00:00

Eli Friedman b4d3c99929 Make sure we aggressively attach nounwind (etc.) to calls to library 
functions of the form __builtin_XXX.

Eric Christopher cf5e83b471 __clear_cache() is varargs and people will occasionally write it without 
arguments. Process only the arguments that people write, but process
all of them.

Chris Lattner 91c08ad14a update for ConstantVector API change.

Chris Lattner dd68bd0a65 revert my ConstantVector patch, it seems to have made the llvm-gcc 
builders unhappy.

John McCall ad7c5c1657 Reorganize CodeGen{Function,Module} to eliminate the unfortunate 
Block{Function,Module} base class.  Minor other refactorings.

Fixed a few address-space bugs while I was there.

Ted Kremenek 582a0999fb Null initialize a few variables flagged by 
clang's -Wuninitialized-experimental warning.
While these don't look like real bugs, clang's
-Wuninitialized-experimental analysis is stricter
than GCC's, and these fixes have the benefit
of being general nice cleanups.

John McCall 20f6ab828a Fix a latent bug where, after emitting an expression statement, we would 
delete the block we began emitting into if it had no predecessors.  We never
want to do this, because there are several valid cases during statement
emission where an existing block has no known predecessors but will acquire
some later.  The case in my test case doesn't inherently fall into this 
category, because we could safely emit the case-range code before the statement
body, but there are examples with labels that can't be fallen into 
that would also demonstrate this bug.

the other floating-point conversion builtins.  Radar 8068427.

Bob Wilson d1767c5c15 LLVM's intrinsics for vpaddl and vpadal have 2 overloaded types.

John McCall 3a7f6926d1 Restore r117403 (fixing IR gen for bool atomics), this time being less 
aggressive about the form we expect bools to be in.  I don't really have
time to fix all the sources right now.

Argyrios Kyrtzidis 073c9cb592 Implement __builtin_ia32_vec_ext_v2si function (required by Qt). 
llvm-svn: 116162
 2010-10-10 03:19:11 +00:00
Bill Wendling 65b2a965fb Add target implementations for the X86 builtins: 
__builtin_ia32_vec_init_v8qi
  __builtin_ia32_vec_init_v4hi
  __builtin_ia32_vec_init_v2si

They are lowered to bitcasts. (These are all ready tested by the gcc testsuite.)

Chris Lattner 64d7f2a014 when expanding a builtin, if the argument is required to be a constant, 
force it to be a constant instead of emitting with EmitScalarExpr.  In
-ftrapv mode, they are not the same.

This fixes rdar://8478728 + PR8221
