RE: Solaris/x86: RTESys_AsmSpinlock.s

Hey J�rg,

this does unfortunately not work either...


vmake 10.02.18 05-01-2004

Here's the vmake generated file:

     1          .file  "RTESys_AsmSpinlock.s"
     2          .align 4
     3          .text
     4          .globl RTESys_AsmTestAndLock
     5          .type  RTESys_AsmTestAndLock,@function
     6  RTESys_AsmTestAndLock:
     7          .movl  4(%esp),%edx
     8          .movl  (%edx), %eax
     9          .movl  $1, %ecx
    10  _lock_again:
    11          lock
    12          cmpxchg %ecx,(%edx)
    13          jne     _lock_again
    14          ret
    15          .globl  RTESys_AsmUnlock
    16          .align  4
    17          .type   RTESys_AsmUnlock,@function
    18  RTESys_AsmUnlock:
    19          .movl   4(%esp),%edx
    20          .movl   (%edx), %eax
    21          .xorl   %ecx,%ecx
    22  _unlock_again:
    23          lock

*sigh*

The assember does not understand the "movl" - same reason why the original
code does not compile, it seems to have very different semantics here.

I think I'll have to search some Intel Solaris assembler guru. Maybe someone
from the Sun/x86 list will help...
