Warning about incompatible GCC version with GCC 4.8.4 #34

Closed v-lopez closed 8 years ago

v-lopez commented 8 years ago

I am execuing abi-compliance-checker from a Ubuntu 14.04 64b machine with GCC 4.8.4, but I get a warning about GCC 4.8.

I've looked at the source code, and afaik it should only affect versions between 4.8.0 and 4.8.2. The problem is that after the warning it sets EMERGENCY_MODE_48 to 1 and changes the behaviour of ACC.

Is it intended that version 4.8.4 is executed with EMERGENCY_MODE_48 enabled?

Hello,

Thank you for reporting the issue.

The EMERGENCY_MODE_48 should not be set for gcc 4.8.4. Seems that this is a bug in the ACC.

Could you please post output of:

gcc -dumpmachine
