Chris Lattner 4f6c81ac68 we don't have to make an explicit copy of a byval argument when
inlining a function if we know that the function does not write
to *any* memory.  This implements test/Transforms/Inline/byval2.ll

Chris Lattner 317e6ba07f Tighten up handling of __func__ and friends: it should be an array
of const char, and it should error if it occurs outside a function.

Is it valid in an objc method?  If so we should handle that too.

Chris Lattner 177977ac19 When forming the squigly underline for a diagnostic, make sure to
verify that the source range corresponds to the current file, not
just the current line.  This allows us to emit:

a.c:1:44: error: invalid operands to binary expression ('double' and 'int *')
double a; int *b; void f(void) { int c = a +
                                         ~ ^

instead of:

a.c:1:44: error: invalid operands to binary expression ('double' and 'int *')
double a; int *b; void f(void) { int c = a +
~                                        ~ ^

for PR1906 (note the leading ~).

Thanks to Neil for noticing this.

Chris Lattner 6da61c2515 Any x86 instruction that reads from an invariant location is invariant.
This allows us to sink things like:
	cvtsi2sd	32(%esp), %xmm1
when reading from the argument area, for example.

Chris Lattner 08af5a9dad implement support for sinking a load out the bottom of a block that
has no stores between the load and the end of block.  This works 
great and sinks hundreds of stores, but we can't turn it on because
machineinstrs don't have volatility information and we don't want to
sink volatile stores :(

Chris Lattner 031f5e1b8c new testcase
llvm-svn: 45888
2008-01-11 23:04:14 +00:00
Duncan Sands b99f44aa5e Do not allow attributes beyond a function's last
parameter, even if it is a varargs function.  Do
allow attributes on the varargs part of a call,
but not beyond the last argument.  Only allow
selected attributes to be on the varargs part of
a call (currently only 'byval' is allowed).  The
reasoning here is that most attributes, eg inreg,
simply make no sense here.

Chris Lattner b5bd924e83 Teach argpromote to ruthlessly hack small byval structs when it can
get away with it, which exposes opportunities to eliminate the memory
objects entirely.  For example, we now compile byval.ll to:

define internal void @f1(i32 %b.0, i64 %b.1) {
entry:
	%tmp2 = add i32 %b.0, 1		; <i32> [#uses=0]
	ret void
}

define i32 @main() nounwind  {
entry:
	call void @f1( i32 1, i64 2 )
	ret i32 0
}

This seems like it would trigger a lot for code that passes around small
structs (e.g. SDOperand's or _Complex)...

Scott Michel a8f67e04bd More CellSPU refinements:
- struct_2.ll: Completely unaligned load/store testing

- call_indirect.ll, struct_1.ll: Add test lines to exercise
   X-form [$reg($reg)] addressing

At this point, loads and stores should be under control (he says
in an optimistic tone of voice.)

Actually were not riding any arguments. Sadly there is no semantic spell checker that is going to safe you from such a mistake.

Arnold Schwaighofer 6cf72fbbaf Improve tail call optimized call's argument lowering. Before this
commit all arguments where moved to the stack slot where they would
reside on a normal function call before the lowering to the tail call
stack slot. This was done to prevent arguments overwriting each other.
Now only arguments sourcing from a FORMAL_ARGUMENTS node or a
CopyFromReg node with virtual register (could also be a caller's
argument) are lowered indirectly.
