Dale Johannesen 763e110a9f Fix .eh table linkage issues on Darwin. Some EH support 
for Darwin PPC, but it's not fully working yet.

Evan Cheng 0cbe920d7c Oops. Debugging code shouldn't have been checked in.

Anton Korobeynikov 2c6387803e Fix PIC jump table codegen on x86-32/linux. In fact, such thing should be applied 
to all targets uses GOT-relative offsets for PIC (Alpha?)

Evan Cheng 7f02cfa599 Clean up sub-register implementation by moving subReg information back to 
MachineOperand auxInfo. Previous clunky implementation uses an external map
to track sub-register uses. That works because register allocator uses
a new virtual register for each spilled use. With interval splitting (coming
soon), we may have multiple uses of the same register some of which are
of using different sub-registers from others. It's too fragile to constantly
update the information.

Evan Cheng 797d56ff17 Much improved pic jumptable codegen: 
Then:
        call    "L1$pb"
"L1$pb":
        popl    %eax
		...
LBB1_1: # entry
        imull   $4, %ecx, %ecx
        leal    LJTI1_0-"L1$pb"(%eax), %edx
        addl    LJTI1_0-"L1$pb"(%ecx,%eax), %edx
        jmpl    *%edx

        .align  2
        .set L1_0_set_3,LBB1_3-LJTI1_0
        .set L1_0_set_2,LBB1_2-LJTI1_0
        .set L1_0_set_5,LBB1_5-LJTI1_0

LJTI1_0:
        .long    L1_0_set_3
        .long    L1_0_set_2

Now:

		...
LBB1_1: # entry
        addl    LJTI1_0-"L1$pb"(%eax,%ecx,4), %eax

		.set L1_0_set_5,LBB1_5-"L1$pb"

Chris Lattner 5e99fd8c0d Add support for the x86-64 'q' regigster modifier, and add support for the 
b/h/w/k/q inline asm memory modifiers, which are just ignored.  This fixes
PR1748 and CodeGen/X86/2007-10-28-inlineasm-q-modifier.ll

function symbol name instead of a codegen-assigned function
number.

Thanks Evan! :-)

Dan Gohman 9da02f5ee2 Remove isReg, isImm, and isMBB, and change all their users to use 
isRegister, isImmediate, and isMachineBasicBlock, which are equivalent,
and more popular.

Bill Wendling 2b8fc31df9 The personality function on Darwin needs a global stub. We then refer to 
that global stub instead of doing the ".set" thingy we were doing before.

Evan Cheng 97057f37a5 - Target PIC style is no longer affected by relocation model. 
- In x86-64 mode, symbols with external linkage (not just symbols which are
  defined externally) requires GOT indirect reference.
- Stylistic code clean up.

Anton Korobeynikov 3f6d52834b * Fix one more bug in PIC codegen: extra load is needed for *all* 
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.

Chris Lattner ae5db00419 add a missing else. This caused globals to be printed as:

Anton Korobeynikov bb162f48ba gcc often inserts it's own names for sections (e.g. 
gnu.linkonce.t.FunctionName). Convert them to "normal" LLVM names,
otherwise linker won't be able to merge them.

llvm-svn: 32958
 2007-01-06 18:24:26 +00:00
Anton Korobeynikov 4efbbc963f Really big cleanup. 
- New target type "mingw" was introduced
- Same things for both mingw & cygwin are marked as "cygming" (as in
gcc)
- .lcomm is supported here, so allow LLVM to use it
- Correctly use underscored versions of setjmp & _longjmp for both mingw
& cygwin
