7142fb87e8 Sometimes tab completion is *not* your friend. Added the wrong file, by 
accident so now I'm correcting it. The script is userloc.pl not userloc.html

49c8521b6e pretty tiny change (looks like adding the HP-UX detection and line number 
changes to me)

- not committing autoconf/configure.ac (oops, already committed that!)
- not committing include/llvm/Config/config.h.in (it remains unchanged)

5041bff028 Added a note about how the type can be omitted in call instructions. 
Added a note about how getelementptr can be used to index into structures
or arrays.
Fixed some typos, spelling, etc.

can't patch it up for c++ (works in C though)

0366a913ad PPC "branch and link" instructions are branches in the PPC sense, but not 
in the LLVM code generator sense (they are calls).  Don't mark them as such,
which fixes the regressions on the ppc tester last night

* Use C++ style casts, not C style casts
* Abstract base classes should have virtual destructor.

2fd2e53f6a Teach reginfo how to deal with ADJSTACKPTRri, allowing us to generate: 
add %ESP, 20
        jmp %EDX  # TAIL CALL

instead of:

        add %ESP, 28

811dc49f55 Add some simplifications for MULH[SU]. This allows us to compile this: 
long %bar(long %X) {
  %Y = mul long %X, 4294967297
  ret long %Y
}

to this:

l1_bar:
        mov %EAX, DWORD PTR [%ESP + 4]
        mov %EDX, %EAX
        add %EDX, DWORD PTR [%ESP + 8]
        ret

instead of:

l1_bar:
        mov %ECX, DWORD PTR [%ESP + 4]
        mov %EDX, 1
        mov %EAX, %ECX
        mul %EDX
        add %EDX, %ECX
        add %EDX, DWORD PTR [%ESP + 8]
        mov %EAX, %ECX
        ret
