Evan Cheng 1d71248392 Darwin API issue: indirect load of external and weak symbols. 
llvm-svn: 24775
 2005-12-17 09:13:43 +00:00
Chris Lattner 866cef563b Add some simple integer patterns. This allows us to compile this: 
int %test(int %A) {
  %B = add int %A, 1
  %C = xor int %B, 123
  ret int %C
}

into this:

test:
        save -96, %sp, %sp
        add %i0, 1, %l0
        xor %l0, 123, %i0
        restore %g0, %g0, %g0
        retl
        nop

for example.  I guess it would make sense to add reg/reg versions too.

Chris Lattner 80a3875bc1 Implement ret with operand, giving us this: 
int %test(int %A) {
  ret int %A
}

llvm-svn: 24773
 2005-12-17 08:15:09 +00:00
Chris Lattner 1136b7a2e0 Add a pattern for 'ret'. This now compiles: 
void %test() { ret void }

:)

llvm-svn: 24767
 2005-12-17 07:17:59 +00:00
Chris Lattner 55f9dbe1ea Use the AsmPrinter for global variable init printing. This eliminates a 
bunch of code and causes V8 to start using the fancy .asciz directive that
the sun assembler supports.
