Bob Wilson 463a05342a Change VDUPLANE DAG combiner to just return the result instead of calling 
CombineTo to avoid putting the result on the worklist.  I don't think it makes
much difference for now, but it might help someday as we add more DAG
combine optimizations.

Bob Wilson 2280674fa9 Combine both VMOVDRR(VMOVRRD) and VMOVRRD(VMOVDRR), instead of just doing one 
of those.  Refactor to share code for handling BUILD_VECTOR(VMOVRRD).
I don't have a testcase that exercises this, but it seems like an obvious
good thing to do.

Bob Wilson b6832a4372 When moving zext/sext to be folded with a load, ignore the issue of whether 
truncates are free only in the case where the extended type is legal but the
load type is not.  If both types are illegal, such as when they are too big,
the load may not be legalized into an extended load.

Bob Wilson e1223fb583 Attempt to fix llvm-gcc build. It was crashing when building gcov.o for an 
ARM cross-compiler on x86, because the MMO size did not match the type size.
This fixes the MMO size and also the size of the stack object to match the
type size.

Argyrios Kyrtzidis ca0d0cd3b9 Implement -Wpadded and -Wpacked. 
-Wpadded warns when undesired padding is introduced in a struct. (rdar://7469556)
-Wpacked warns if a struct is given the packed attribute, but the packed attribute has no effect
  on the layout or the size of the struct. Such structs may be mis-aligned for little benefit.

The warnings are emitted at the point where layout is calculated, that is at RecordLayoutBuilder.
To avoid calculating the layouts of all structs regardless of whether they are needed or not,
I let the layouts be lazily constructed when needed. This has the disadvantage that the above warnings
will be emitted only when they are used for IR gen, and not e.g with -fsyntax-only:

$ cat t.c
struct S {
  char c;
  int i;
};
void f(struct S* s) {}

$ clang -fsyntax-only -Wpadded t.c
$ clang -c -Wpadded t.c -o t.o
t.c:3:7: warning: padding struct 'struct S' with 3 bytes to align 'i' [-Wpadded]
  int i;
      ^
1 warning generated.

This is a good tradeoff between providing the warnings and not calculating layouts for all
structs in case the user has enabled a couple of rarely used warnings.

 2010-09-22 06:09:31 +00:00
Chris Lattner bd85725341 Fix an inconsistency in the x86 backend that led it to reject "calll foo" on 
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.
