Evan Cheng f9a4c690de - Off by one bugs in maximum displacement calculation / testing.
- In thumb mode, a new constpool island BB size should be 4 + 2 to
  compensate for the potential padding due to alignment requirement.

Anton Korobeynikov 1b4e6015b4 Fixed uninitialized stuff inside LegalizeDAG. Fortunately, the only
affected part is codegen of "memove" inside x86 backend. This fixes

Evan Cheng 06736d0f88 .set pc relative displacement bug: label should be moved down one instruction
to just before the add r1, pc:

Before:
        .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
LPCRELL0:
        mov r1, #PCRELV0
        add r1, pc

Now:
        .set PCRELV0, (LJTI1_0_0-(LPCRELL0+4))
        mov r1, #PCRELV0
LPCRELL0:
        add r1, pc

2007-02-01 01:56:43 +00:00
Evan Cheng e7e966de5e Special epilogue for vararg functions. We cannot do a pop to pc because
there follows a sp increment for the va register save region. Instead issue
a separate pop to another register, increment sp, and then return:
        pop {r4, r5, r6, r7}
        pop {r3}
        add sp, #3 * 4
        bx r3
