#pragma GCC pop_options

Bug #1534360 reported by Liviu Ionescu on 2016-01-14

GNU Arm Embedded Toolchain

Bug Description

Attempts to use 'pop_options' result in

../src/main.cpp:78:9: warning: #pragma GCC target is not supported for this machine [-Wpragmas]
 #pragma GCC pop_options

Is this intentional for ARM, or it is a bug?

The 'push_options' is ok, but without pop, I need to move this sequence at the end of the file.

#pragma GCC push_options
#pragma GCC optimize("-O0")

#pragma GCC pop_options

Changed in gcc-arm-embedded:
status: New → Confirmed

Duplicated as this GCC bugzila:

Now that target_attribute has been enabled in trunk, this issue might solvable now.

Hi Liviu,

I can confirm this happens on the 5.2 release. It was fixed on trunk with the following patch:
https://gcc.gnu.org/ml/gcc-patches/2015-10/msg01261.html which was committed in r228794.

Ill look into backporting it to gcc-5.

Best Regards,
