202293 - The Win32 gcc port of NSS should use x86 assembly code

Status: NEW

(NSS :: Libraries, defect, P3)

Description

[Wan-Teh Chang]

The Win32 gcc port of NSS should use x86 assembly code
in the "freebl" library.  We currently have:
- mpi_x86.asm: for Win32 with MSVC and OS/2 with VACPP;
- mpi_x86.s: for Linux x86;
- mpi_i86pc.s: for Solaris x86.

None of these work as is.  Here is what cls said about
his attempt to use mpi_x86.s:

  It turns out that GNU ld doesn't have support for stosd.
  It expects to use stosl but calling stosl on win32 causs
  a segfault.

Is OS/2 hitting this problem with their transition to gcc3? Or does OS/2 gcc not
use GNU binutils?

FYI, I also needed this rule to translate mpi_x86.s since win32 requires leading
underscores on symbols.

+#mpi_x86_win32.s: mpi_x86.s
+#	cat $< | sed -e 's|^\.type|#.type|' -e 's|s_mpv_|_s_mpv_|g' > $@

OS/2 with gcc does use GNU binutils . From what I can tell, the OS/2 gcc build
of NSS is currently using the C implementation of mpi rather than the x86
assembly code (.s versoin). I haven't tried using the mpi_x86.s with it yet.
Changing description to reflect both Win32 & OS/2.

Please open a separate bug for the OS/2 gcc port.
