eh_frame missing.

eh_frame missing.

[Girish Shilamkar]

Hi,
	I compiled a .S but the problem is that the executable doesn't show
eh_frame section even though the code has CFI macros.
The instruction I am using to compile is :
	gcc -Wl,-g -Wa,-g  -v -g -o temp temp.S

Would you please let me know if I have missed something ?


Thanks & Regards,
-Girish

What does temp.S look like ?

Which version of gas and ld are you using ?
