Nick Lewycky 974e12b2d3 Remove includes of Support/Compiler.h that are no longer needed after the 
VISIBILITY_HIDDEN removal.

llvm-svn: 85043
 2009-10-25 06:57:41 +00:00
Nick Lewycky 02d5f77d26 Remove VISIBILITY_HIDDEN from class/struct found inside anonymous namespaces. 
Chris claims we should never have visibility_hidden inside any .cpp file but
that's still not true even after this commit.

Daniel Dunbar 0dd5e1ed39 More migration to raw_ostream, the water has dried up around the iostream hole. 
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

Gabor Greif 258232fb80 Second installment of "BasicBlock operands to the back" 
changes.

For InvokeInst now all arguments begin at op_begin().
The Callee, Cont and Fail are now faster to get by
access relative to op_end().

This patch introduces some temporary uglyness in CallSite.
Next I'll bring CallInst up to a similar scheme and then
the uglyness will magically vanish.

This patch also exposes all the reliance of the libraries
on InvokeInst's operand ordering. I am thinking of taking
care of that too.

Devang Patel a05633e105 Now Attributes are divided in three groups 
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

This patch requires corresponding changes in llvm-gcc and clang.

Devang Patel 4c758ea3e0 Large mechanical patch. 
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.

Matthijs Kooijman c893bf472d Allow deadargelim to change return types even though now values were dead. This 
again canonicalizes {i32} into i32 and {} into void.

 2008-07-15 14:42:31 +00:00
Matthijs Kooijman 5e8c022e21 Revert r53606. It turns out that explicitely tracking the liveness of the 
return value as a whole in deadargelim is really not needed now that we simply
rebuild the old return value and actually prevents some canonicalization from
taking place.

This revert stops deadargelim from changing {i32} into i32 for now, but I'll
fix that next.

llvm-svn: 53609
 2008-07-15 14:39:36 +00:00
Matthijs Kooijman c1da874478 Make deadargelim a bit less smart, so it doesn't choke on nested structs as 
return values that are still (partially) live. Instead of updating all uses of
a call instruction after removing some elements, it now just rebuilds the
original struct (With undef gaps where the unused values were) and leaves it to
instcombine to clean this up.

The added testcase still fails currently, but this is due to instcombine which
isn't good enough yet. I will fix that part next.

Matthijs Kooijman 04d4c328ac Don't use isa when we can reuse a previous dyn_cast.

Matthijs Kooijman 84194b6768 Make DeadArgElim keep liveness of the return value as a whole in addition to 
only the liveness of partial return values (for functions returning a struct).
This is more explicit to prevent unwanted changes in the return value. 

In particular, deadargelim now canonicalizes a function returning {i32} to
returning i32 and {} to void, if the struct returned is not used in its
entirety, but only the single element is used.

 2008-07-15 13:36:06 +00:00
Matthijs Kooijman 79a8eb547c Let DAE keep a list of live functions, instead of simply marking all arguments 
and return values live for those functions. This doesn't change anything yet,
but prepares for the coming commits.

Matthijs Kooijman e0f3ab82c4 Restructure dead argument elimination, try #3 :-) 
Rewrite the DeadArgumentElimination pass, to use a more explicit tracking of
dependencies between return values and/or arguments. Also make the handling of
arguments and return values the same.

The pass now looks properly inside returned structs, but only at the first
level (ie, not inside nested structs).

This version fixed a few more bugs and was cleaned up a bit. It now passes all
of LLVM's testing, and should still pass SPEC2006. There is still a minor bug
with regard to returning nested structs. Since there is currently nothing that
emits such IR, I will fix that in a seperate commit (partly because it requires
a non-trivial fix).
