SIGILL with clang

[ROHIT KUMAR]

Hey folks, 

I am migrating our huge Android code base from GCC(Eclipse IDE) to clang(Android Studio). 

Error: SIGILL (signal SIGILL: illegal instruction)

At a weird line in the code, I am getting this error. which points to a closing curly bracket of an if condition. After googling, I am assuming it is some kind of architecture flag issue. I am using same flags which were used for GCC. 

Note: I am currently working on Arm build. 

Here are the architecture flags for ARM7:

-march=armv7-a -mfloat-abi=softfp -mfpu=vfpv3-d16 -mtune=cortex-a8 -mthumb -DTARGET_THUMB2

Can anyone help me debug this issue? Is there any issue with the flags with clang?

Thanks,

Rohit Kumar

It looks like you already got your answer from the clang mailing list. I'd recommend using -Werror=return-type.
