Chris Lattner a1b39fa5ad * Make some methods more const correct. 
* Change the FunctionCalls and AuxFunctionCalls vectors into std::lists.
  This makes many operations on these lists much more natural, and avoids
  *exteremely* expensive copying of DSCallSites (e.g. moving nodes around
  between lists, erasing a node from not the end of the vector, etc).

With a profile build of analyze, this speeds up BU DS from 25.14s to
12.59s on 176.gcc.  I expect that it would help TD even more, but I don't
have data for it.

This effectively eliminates removeIdenticalCalls and children from the
profile, going from 6.53 to 0.27s.

Chris Lattner 800b72445f This file was schizophrenic when it came to representing sizes. In some 
cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts.  In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.

This patch unifies all of the sizes to use size_t instead.

Chris Lattner be62e72273 Before doing expensive global analysis, check to make sure the pointer is 
not invalidated on entry and on exit of the block.  This fixes some N^2
behavior in common cases, and speeds up gcc another 5% to 22.35s.

Chris Lattner fe7a9a242e Minor simplification/speedup. Replaces a set lookup with a pointer comparison. 
This speeds up 176.gcc from 25.73s to 23.48s, which is 9.5%

llvm-svn: 19907
 2005-01-29 06:20:55 +00:00
Chris Lattner 787aed675d Eliminate generality that is not buying us anything. In particular, this 
will cause us to miss cases where the input pointer to a load could be value
numbered to another load.  Something like this:


  %X = load int* %P1
  %Y = load int* %P2

Those are obviously the same if P1/P2 are the same.  The code this patch
removes attempts to handle that.  However, since GCSE iterates, this doesn't
actually buy us anything: GCSE will first replace P1 or P2 with the other
one, then the load can be value numbered as equal.

Removing this code speeds up gcse a lot.  On 176.gcc in debug mode, this
speeds up gcse from 29.08s -> 25.73s, a 13% savings.

Chris Lattner debae1e3c3 Allow the FP stackifier to completely ignore functions that do not use FP at 
all.  This should speed up the X86 backend fairly significantly on integer
codes.  Now if only we didn't have to compute livevar still... ;-)

Chris Lattner 90b7c13f3a Remove the 3 HACK HACK HACKs I put in before, fixing them properly with 
the new TLI that is available.

Implement support for handling out of range shifts.  This allows us to
compile this code (a 64-bit rotate):

unsigned long long f3(unsigned long long x) {
  return (x << 32) | (x >> (64-32));
}

into this:

f3:
        mov %EDX, DWORD PTR [%ESP + 4]
        mov %EAX, DWORD PTR [%ESP + 8]
        ret

GCC produces this:

$ gcc t.c -masm=intel -O3 -S -o - -fomit-frame-pointer
..
f3:
        push    %ebx
        mov     %ebx, DWORD PTR [%esp+12]
        mov     %ecx, DWORD PTR [%esp+8]
        mov     %eax, %ebx
        mov     %edx, %ecx
        pop     %ebx
        ret

The Simple ISEL produces (eww gross):

f3:
        sub %ESP, 4
        mov DWORD PTR [%ESP], %ESI
        mov %EDX, DWORD PTR [%ESP + 8]
        mov %ECX, DWORD PTR [%ESP + 12]
        mov %EAX, 0
        mov %ESI, 0
        or %EAX, %ECX
        or %EDX, %ESI
        mov %ESI, DWORD PTR [%ESP]
        add %ESP, 4
        ret
