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) leaq6(%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 leaq6(%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) leaq6(%rsp), %rsi call*16(%rax) addq$8, %rsp ret Kurt --5vNYLRcllDrimb99 Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename="SDL_endian.i" # 1 "../../../SDL-1.2.7+1.2.8cvs20041007/src/endian/SDL_endian.c" # 1 "" # 1 "" # 1 "../../../SDL-1.2.7+1.2.8cvs20041007/src/endian/SDL_endian.c" # 30 "../../../SDL-1.2.7+1.2.8cvs20041007/src/endian/SDL_endian.c" # 1 "../../../SDL-1.2.7+1.2.8cvs20041007/include/SDL_endian.h" 1 # 45 "../../../SDL-1.2.7+1.2.8cvs20041007/include/SDL_endian.h" # 1 "/usr/include/stdio.h" 1 3 4 # 28 "/usr/include/stdio.h" 3 4 # 1 "/usr/include/features.h" 1 3 4 # 295 "/usr/include/features.h" 3 4 # 1 "/usr/include/sys/cde
