Re: [cdt-dev] Inline Assembly?
|
The parser can handle function-style asm constructs. However, because this is not standard c or c++, it does not do that per default. To turn the feature on, you need to use a custom language (extend GPPLanguage or GCCLanguage and override getParserExtensionConfiguration()).
You may want to create a bug to make the parser handle this c++ extension per default.

Subject: [cdt-dev] Inline Assembly?
Importance: Low
Hi folks,
We have some C files, which have Inline Assembly for ePPC.
Currently, I have lots of Syntax Errors there. I currently have
undefined __asm in Project Settings so at least the function itself has
not the syntax error set.
Which way is CDT handling Inline Assembly, if at all?
__asm void foo(void)
{
lis r0, 0x4000@ha
ori r0,r0, 0x1000@l
mfspr r3, SPR_XYZ
stw r3, 0(r1)
}
or rather
void foo(void)
{
__asm {
lis r0, 0x4000@ha
ori r0,r0, 0x1000@l
mfspr r3, SPR_XYZ
stw r3, 0(r1)
};
}
or gnu style like
void foo(void)
{
asm(
"lis r0, 0x4000@ha"
"ori r0,r0, 0x1000@l"
"mfspr r3, SPR_XYZ"
"stw r3, 0(r1)"
, /*in*/ : /*out*/: /*clobber*/ );
}
And how are the assembler instructtions setup?
