Evan Cheng c5549fc3a0 Instead of adding copyfromreg's to handle physical definitions. Now isel can 
simply specify them as results and let scheduledag handle them. That
is, instead of
SDOperand Flag = DAG.getTargetNode(Opc, MVT::i32, MVT::Flag, ...)
SDOperand Result = DAG.getCopyFromReg(Chain, X86::EAX, MVT::i32, Flag)

Just write:
SDOperand Result = DAG.getTargetNode(Opc, MVT::i32, MVT::i32, ...)

And let scheduledag emit the move from X86::EAX to a virtual register.

Dan Gohman 54ec4bfa5f Change the x86 assembly output to use tab characters to separate the

tests accordingly.

Chuck Rose III 1a39a2d13d VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control. 
This commit fixes two things.  One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop.  I fixed these 
by renaming one of the two variables.  Additionally, I've made the Function*->ExFunc map in 
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown.  In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.

llvm-svn: 40558
 2007-07-27 18:26:35 +00:00
Chuck Rose III 8e9869716c Updates to the VStudio project files: 
1. Switch from VStudio 2k3 to VStudio 2k5

2. All pdb files now will be placed as $(OutputDir)/$(ProjectName).pdb.  This puts them alongside the 
binaries with the same base name as the binary.  If you need to copy the results of your llvm build 
into another project's tree, this will simplify that process.

3. Recent files added to the tree were added to the proejects within the VStudio project

4. Project build dependency order fixed so that the build can take place in one pass.  A generated
file was not being built at the correct time, causing a build error in about half the projects until
the build was run a second time.

Note you will need flex and bison installed an in your path in order to build properly.

Dan Gohman 4788552deb Re-apply 40504, but with a fix for the segfault it caused in oggenc:

a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.

Duncan Sands 07c9066238 As the number of parameter attributes increases, 
Verifier::visitFunction is suffering a combinatorial

using attribute masks.  While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail.  Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).
