__asm__ and -fPIC problem

[Marcus Meissner]

Hi,

Compiling WINE with gcc-2.95.1 and gcc-latest (via webfrontend) has some
strange __asm__ complaints. I am not sure whether this is a bug on our (WINE)
side, or a gcc bug. I've attached the small testcase I could extract.

It only happens with -fPIC, and vanishes with -O2.

$ gcc -v
gcc version 2.95.1 19990816 (release)
$ gcc -c xx.c
$ gcc -c xx.c -fPIC
xx.c: In function `DPMI_CallRMCBProc':
xx.c:36: Invalid `asm' statement:
xx.c:36: fixed or forbidden register 1 (dx) was spilled for class GENERAL_REGS.
$ gcc -c xx.c -fPIC -O2
$

Webfrontend:
no options: no compile errors.
-fPIC:
	/tmp/@19715.1: In function `DPMI_CallRMCBProc':
        /tmp/@19715.1:36: Can't find a register in class `GENERAL_REGS' while reloading `asm'.
-fPIC -O2: no compile errors.

Ciao, Marcus
