2019-07-31[Arm][CMSE]Add warn_unused_return attribute to cmse functionsJoel Hutton2-0/+6
At present it is possible to call the CMSE functions for checking addresses (such as cmse_check_address_range) and forget to check/use the return value. This patch makes the interfaces more robust against programmer error by marking these functions with the warn_unused_result attribute. With this set, any use of these functions that does not use the result will produce a warning. This produces a warning on default warn levels when the result of the cmse functions is not used. For the following function: void foo() { int *data; cmse_check_address_range((int*)data, 0, 0); } The following warning is emitted: warning: ignoring return value of 'cmse_check_address_range' declared with attribute 'warn_unused_result' [-Wunused-result] 6 | cmse_check_address_range((int*)data, 0, 0); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcc/ChangeLog: 2019-07-31 Joel Hutton <Joel.Hutton@arm.com> * config/arm/arm_cmse.h (cmse_nonsecure_caller): Add warn_unused_result attribute.

2019-06-06Darwin, PowerPC, libgcc - Ensure unwinder is built with altivec enabled.Iain Sandoe2-0/+8
When libgcc is built on Darwin, it is usually built for the earliest potential target (Darwin8, 10.4). Build for that revision default to assuming that the processor might be G3 (without vector ops) and there is an outlined function used for save/restore that checks whether the processor is G3 or G4+ at run- time. However, the unwinder itself needs to be built with the assumption of vector usage so that the relevant outlined functions are called. 2019-06-06 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/t-darwin: Ensure that the unwinder is built with altivec enabled.
