PackedTypes as a side-effect.

Chris Lattner 335b46dd20 LowerReturn now doesn't have to handle f32 returns.

Chris Lattner 222ceabbee If the target doesn't support f32 natively, insert the FP_EXTEND in target-indep 
code, so that the LowerReturn code doesn't have to handle it.

int vs uint

Jeff Cohen 8ca86aa918 Update Windows version of config.h to note availability of floor/floorf/ceil/ceilf. 
Also pulled Windows-specific modifications to config.h.in to a separate file, so
that changes to it trigger regeneration of config.h (which doesn't happen when the
custom build step for it changes).

Evan Cheng 9a4ab9660f Added a load folding bug test case. 
llvm-svn: 25472
 2006-01-20 01:12:23 +00:00
Evan Cheng e272b4ec17 Prevent folding of a node with multiple uses if the node already folds a load! 
Here is an example where the load ended up being done twice:

%A = global uint 0

uint %test(uint %B, ubyte %C) {
	%tmp = load uint *%A;
	%X = shl uint %tmp, ubyte %C
	%Cv = sub ubyte 32, %C
	%Y = shr uint %B, ubyte %Cv
	%Z = or uint %Y, %X
	store uint %Z, uint* %A
	ret uint %Z
}

==>

	subl $4, %esp
	movl %ebx, (%esp)
	movl 8(%esp), %edx
	movl A, %eax
	movb 12(%esp), %bl
	movb %bl, %cl
	shldl %cl, %edx, %eax
	movb %bl, %cl
	shldl %cl, %edx, A
	movl (%esp), %ebx
	addl $4, %esp
	ret

Evan Cheng a15731cd50 Use pattern information to determine whether the use expects this 
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.

Reid Spencer ade182125f For PR696: 
Don't do floor->floorf conversion if floorf is not available. This checks
the compiler's host, not its target, which is incorrect for cross-compilers
Not sure that's important as we don't build many cross-compilers.

friends are actually detected.

Reid Spencer bf31906660 1. Identify bytecode modules that have upgraded intrinsics by setting a 
boolean flag if we read a function prototype that needs upgrading.
2. Don't upgrade the CallInst instruction until after its been inserted
   into the basic block, and only if we know that we have seen an
   upgraded intrinsic function.

 2006-01-19 07:02:16 +00:00
Reid Spencer 75b9567671 Don't forget about casting the result of an upgraded call to an intrinsic 
in the case where it needs to cast back to a signed type.

llvm-svn: 25447
 2006-01-19 07:00:29 +00:00
Reid Spencer 6b68c057b4 1. Documentation upgrade. 
2. Have UpgradeInstrinicCall return an Instruction* instead of a CallInst*
   and return the needed CastInst* if the result of the upgraded call needs
   to be casted back to a signed type.

llvm-svn: 25446
