667186f10f Make sure to remove all dead type names from the symbol table, not just 
struct types.  This fixes Regression/CodeGen/CBackend/2005-03-08-RecursiveTypeCrash.ll,
a crash on Java output that Alkis reported.

4439f1686f Print -X like this: 
double test(double l1_X) {
  return (-l1_X);
}

instead of like this:

double test(double l1_X) {
  return (-0x0p+0 - l1_X);
}

8074739aa2 Do not lower malloc's to pass "sizeof" expressions like this: 
ltmp_0_7 = malloc(((unsigned )(&(((signed char (*)[784])/*NULL*/0)[1u]))));

Instead, just emit the literal constant, like this:

  ltmp_0_7 = malloc(784u);

This works around a bug in ICC 8.1 compiling the CBE generated code.  :-(

bf72146607 Fix volatile load/store of pointers. Consider this testcase: 
void %test(int** %P) {
  %A = volatile load int** %P
  ret void
}

void %test2(int*** %Q) {
  %P = load int*** %Q
  volatile store int** %P, int*** %Q
  ret void
}

instead of emitting:

void test(int **l1_P) {
  int *l2_A;

  l2_A = (int **((volatile int **)l1_P));
  return;
}
void test2(int ***l2_Q) {
  int **l1_P;

  l1_P = *l2_Q;
  *((volatile int ***)l2_Q) = l1_P;
  return;
}

... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):

void test(int **l1_P) {
  int *l3_A;

  l3_A = *((int * volatile*)l1_P);
  return;
}
void test2(int ***l2_Q) {
  int **l1_P;

  l1_P = *l2_Q;
  *((int ** volatile*)l2_Q) = l1_P;
  return;
}

0ba9295e3c Small performance improvement in generated C code: 
Instead of unconditionally copying all phi node values into temporaries for
all successor blocks, generate code that will determine what successor
block will be called and then copy only those phi node values needed by
the successor block.

This seems to cut down namd execution time from being 8% higher than GCC to
4% higher than GCC.

caf0d76a8a 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.

43abe1a0d8 Paper over CBackend/2004-08-09-va-end-null.ll 
Note that this indicates a serious problem with the way we are emitting varargs,
but this should not be properly fixed until after 1.3.

This patch SHOULD go into 1.3.

1649c7d308 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>

42730da855 <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!
