Package: gcc-3.3
Version: 3.3.5-4
Hi,
The libsdl1.2 package is currently failing to build on amd64.
The problem seem to be that gcc generates incorrect assembler, or
atleast assember that as from binutils version 2.15-5 has a
problem with.
The attached file compiled with -O2 -S gives the following
assembler:
.LFE28:
.size SDL_WriteLE16, .-SDL_WriteLE16
.p2align 4,,15
.globl SDL_WriteBE16
.type SDL_WriteBE16, @function
SDL_WriteBE16:
.LFB30:
subq $8, %rsp
.LCFI7:
movl $1, %ecx
movl $2, %edx
movw %si, 6(%rsp)
#APP
xchgb %sil,%ax
#NO_APP
movw %si, 6(%rsp)
leaq 6(%rsp), %rsi
call *16(%rdi)
addq $8, %rsp
ret
As gives the following error:
SDL_endian.S: Assembler messages:
SDL_endian.S:136: Error: suffix or operands invalid for `xchg'
Which is the line: xchgb %sil,%ax
The same generated with -O1 -S gives:
.LFE28:
.size SDL_WriteLE16, .-SDL_WriteLE16
.globl SDL_WriteBE16
.type SDL_WriteBE16, @function
SDL_WriteBE16:
.LFB30:
subq $8, %rsp
.LCFI7:
movw %si, 6(%rsp)
movl %esi, %eax
#APP
xchgb %al,%ah
#NO_APP
movw %ax, 6(%rsp)
movl $1, %ecx
movl $2, %edx
leaq 6(%rsp), %rsi
call *16(%rdi)
addq $8, %rsp
ret
The same SDL_Swap16() function is used in both SDL_ReadBE16() and
SDL_WriteBE16(). The call generated code for SDL_ReadBE16 always
has "xchgb %al,%ah".
The same thing tried with gcc-3.4 -O2 also fails and generates
this instead:
.LFE21:
.size SDL_WriteLE16, .-SDL_WriteLE16
.p2align 4,,15
.globl SDL_WriteBE16
.type SDL_WriteBE16, @function
SDL_WriteBE16:
.LFB22:
subq $8, %rsp
.LCFI7:
movq %rdi, %rax
movl $1, %ecx
movw %si, 6(%rsp)
movl $2, %edx
#APP
xchgb %sil,%si
#NO_APP
movw %si, 6(%rsp)
leaq 6(%rsp), %rsi
call *16(%rax)
addq $8, %rsp
ret
