Specifying the -gsplit-dwarf option

Hello

Does the 4.9.3 compiler support the -gsplit-dwarf option?  I am using the gold linker, and I have specified this option 
using both the -Wc,-gsplit-dwarf and just -gsplit-dwarf, but I do not seem to get a dwo file generated. 

Thanks,
Rodney

RE: Specifying the -gsplit-dwarf option

This option is handled by the compiler driver, so using gcc directly will work but qcc doesn't currently handle it so it
 will essentially end up being silently ignored.

Re: RE: Specifying the -gsplit-dwarf option

Hello

Thanks for the response Michael.  Would the -Wc,-gsplit-dwarf option not pass it to the gcc compiler? 

Thanks,
Rodney

It will pass it to the compiler (cc1) directly, not through the compiler driver (gcc) that has the logic to handle the 
option. In order to support this, qcc would need to have some code added to handle the option in a similar fashion.

Re: RE: RE: Specifying the -gsplit-dwarf option

Hello

Ah I see.  So how do I invoke gcc directly?  I tried running arm-unknown-nto-qnx6.6.0eabi-gcc on a simple test.c file, 
but the collect2 failed because it didn't recognize the -plugin option. 

Thanks,
Rodney

Re: RE: RE: Specifying the -gsplit-dwarf option

So this looks like it is a bug with the 4.9.3 compiler.  If I run the 4.8.3 compiler, then I can compile a test 
application just fine.
