2019-07-31[Arm][CMSE]Add warn_unused_return attribute to cmse functionsJoel Hutton1-0/+1
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 Sandoe1-0/+3
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.

2018-12-19[ARM] Optimize executable size when using softfloat fmul/dmulThomas Preud'homme4-15/+52
Softfloat single precision and double precision floating-point multiplication routines in libgcc share some code with the floating-point division of their corresponding precision. As the code is structured now, this leads to *all* division code being pulled in an executable in softfloat mode even if only multiplication is performed. This patch create some new LIB1ASMFUNCS macros to also build files with just the multiplication and shared code as weak symbols. By putting these earlier in the static library, they can then be picked up when only multiplication is used and they are overriden by the global definition in the existing file containing both multiplication and division code when division is needed. The patch also removes changes made to the FUNC_START and ARM_FUNC_START macros in r218124 since the intent was to put multiplication and division code into their own section in a later patch to achieve the same size optimization. That approach relied on specific section layout to ensure multiplication and division were not too far from the shared bit of code in order to the branches to be within range. Due to lack of guarantee regarding section layout, in particular with all the possibility of linker scripts, this approach was chosen instead. This patch keeps the two testcases that were posted by Tony Wang on the mailing list to implement this approach and adds a new one. 2018-12-19 Thomas Preud'homme <thomas.preudhomme@linaro.org> libgcc/ * /config/arm/lib1funcs.S (FUNC_START): Remove unused sp_section parameter and corresponding code.

Currently, .cfi_endproc and FUNC_END(__trampoline_setup) are placed inside the #else branch of an "#if defined (__VXWORKS__) ...", so non-pic vxworks does not get proper CFI nor a .size directive for __trampoline_setup.

There are a few places in libgcc assembly where we don't emit call frame information for functions, potentially breaking unwinding from asynchronous signal handlers. This patch fixes them. Although I patch tramp.S there is no attempt made to provide CFI for the actual trampoline on the stack. Doing that would require generating CFI at run time and both registering and deregistering it, which is probably not worth doing since it would significantly slow down the call. * config/rs6000/morestack.S (__stack_split_initialize), (__morestack_get_guard, __morestack_set_guard), (__morestack_make_guard): Provide CFI covering these functions. * config/rs6000/tramp.S (__trampoline_setup): Likewise.
