Devang Patel d491198000 Loop unswitch preserves dom info. 
Use simple analysis interface to preserve analysis info maintained by other loop passes.

Devang Patel b98a097ae9 Implement Simple Analysis interfaces - cloneBasicBlockAnalysis and deleteAnalysisValue. 
llvm-svn: 40626
 2007-07-31 08:01:41 +00:00
Devang Patel cc2b233b62 Introduce Simple Analysis interface for loop passes. 
Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

Chris Lattner 49820d63dc Oops, I committed the wrong file before. This expands the description of 
type.

Reid Spencer 4f178405ad Allow the INREG parameter attribute to be added to functions. This permits the 
function result to be passed in a register. This implements the GCC regparm
function attribute for llvm by translation to the InReg parameter attribute 
and fixes test/CFrontend/2002-07-30-SubregSetAssertion.c

llvm-svn: 40619
 2007-07-31 06:37:27 +00:00
Reid Spencer 160e4faedc The InReg parameter attribute is valid on function results. The llvm-gcc-4.0 
front end converts regparm attribute on the gcc function into InReg attribute 
on the llvm function. This fixes test/CFrontend/2002-07-30-SubrefSetAssertion.c

Reid Spencer 32046f7b05 Regenerate for __dso_handle, per Anton's request. 
llvm-svn: 40601
 2007-07-30 20:13:24 +00:00
Anton Korobeynikov 7ac2521021 Add detection of __dso_handle presence during configure. Use this information in the 
JITer (short path is added for darwin). This is needed to properly JIT llvm-gcc-4.2-built
binaries, since cxa_atexit is enabled by default on much more targets.

Chris Lattner fedeaa3045 Don't use canonical type for sema here. In 
void func() {
typedef int foo;
foo *Y;
**Y; // error
}

we now get:
indirection requires pointer operand ('foo' invalid)
instead of:
indirection requires pointer operand ('int' invalid)

Owen Anderson 212d5c27f6 Use more caching when computing non-local dependence. This makes bzip2 not

Steve Naroff ddf5a1d7a6 Implement pretty diagnostics when doing on-the-fly vector sizing (for vector component access). 
For example, before this commit, the following diagnostics would be emitted...

ocu.c:49:12: error: incompatible types assigning 'float  __attribute__((ocu_vector_type(3)))' to 'float4'
    vec4_2 = vec4.rgb; // shorten
    ~~~~~~ ^ ~~~~~~~~
ocu.c:51:7: error: incompatible types assigning 'float  __attribute__((ocu_vector_type(2)))' to 'float'
    f = vec2.xx; // shorten
    ~ ^ ~~~~~~~

Now, the diagnostics look as you would expect...

ocu.c:49:12: error: incompatible types assigning 'float3' to 'float4'
    vec4_2 = vec4.rgb; // shorten
    ~~~~~~ ^ ~~~~~~~~
ocu.c:51:7: error: incompatible types assigning 'float2' to 'float'
    f = vec2.xx; // shorten
    ~ ^ ~~~~~~~
