665825e58e The first hunk corrects a bug when printing undef null values. We would print 
0->field, which is illegal.  Now we print ((foo*)0)->field.

The second hunk is an optimization to not print undefined phi values.

from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

but this should not be properly fixed until after 1.3.

This patch SHOULD go into 1.3.

a9d790c831 Temporarily disable this code, as it is emitting LLVM_NAN("nan") which results in a call to the 
glibc 'nan' function because the initializer is not a string.  This breaks when used in a global
initializer.  Try compiling this testcase for example:

%X = global float <some nan value>

8fcf797f79 <alloca.h> on cygwin pulls in a ton of stuff (macros and function protos) 
that we REALLY don't want in the CBE code.

it does on linux.  Yaay!

9d1af97d02 Fix the big regression that has been killing the nightly tester these last 
few days.  Apparently the old symbol table used to auto rename collisions in
the type symbol table and the new one does not.  It doesn't really make sense
for the new one to do so, so we just make the client do it.

05b15fb075 TargetCacheInfo has been removed; its only uses were to propagate a constant 
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.

e42cde2a14 Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some 
hacks can be banished.  Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs).  Yaay!

94f4f8ea10 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or 
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less

01b2d61311 Fixed the CBE on Solaris/Sparc. We need to define the return value of 
the write() system call because it returns 64 bits on Solaris 64 bit,
and an implicit return value of int says it returns 32 bits.
Admittedly, this is a bit of a hack.

c59c118e44 ISO 9899 7.13.2.1 (3) says that "[...] the values of objects of automatic 
storage duration that are local to the function containing the invocation of the
[...] setjmp macro that do not have volatile-qualified type and have been
changed between the setjmp invocation and longjmp call are indeterminate."

As such, we have to mark all variables in a function that uses 'invoke' as
volatile.

This fixes PR77

54f6032dae - Fixed name mangling conditions to handle 'linkonce' linkage type. In 
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

a8ab89e3da Fairly major change: emit fixed sized allocas in the entry block as a variable, 
instead of a variable pointer and an alloca.  All accesses to the variable then
use the address-of operator to access it.  This plays better with the internal
GCC code generation phases, which bail early on functions which contain allocas.
It also makes the code a bit easier to read.
