2019-07-31PR c++/90538 - multiple expansions of capture packsJason Merrill7-53/+91
Previously, with init-capture the type of the closure field was a DECLTYPE_TYPE of the initializer. But since each time we tsubst a lambda we get a different lambda, that meant that if the initializer is a lambda, we'd end up with different closure types in the field and initializer after substitution (PR 87322). We dealt with this by remembering the lambda instantiation within each pack expansion element, using local_specialization_stack to separate the elements. But that broke this testcase, because it lost lambda capture proxies that also use local_specializations. So, this patch removes the local_specializations changes from that patch and fixes 87322 differently, by giving init-capture fields 'auto' type and doing deduction later. There's a bit of a kludge to get the right number of fields by pretending that 'auto...' uses the parameter packs from the initializer, but it does the trick. * cp-tree.h (DECLTYPE_FOR_INIT_CAPTURE): Remove. * lambda.c (add_capture): Copy parameter packs from init. (lambda_capture_field_type): Always use auto for init-capture. * pt.c (uses_parameter_packs): Return tree. (tsubst) [DECLTYPE_TYPE]: Remove init-capture handling.

2019-07-31[Arm][CMSE]Add warn_unused_return attribute to cmse functionsJoel Hutton6-0/+28
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.

2019-07-31Make lra use per-alternative earlyclobber infoRichard Sandiford5-57/+58
lra_insn_reg and lra_operand_data have both a bitmask of earlyclobber alternatives and an overall boolean. The danger is that we then test the overall boolean when really we should be testing for a particular alternative. This patch gets rid of the boolean and tests the mask against zero when we really do need to test "any alternative might be earlyclobber". (I think the only instance of that is the LRA_UNKNOWN_ALT handling in lra-lives.c:reg_early_clobber_p.) This is needed (and tested) by an upcoming SVE patch. 2019-07-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * lra-int.h (lra_operand_data): Remove early_clobber field.

My previous change to the Thumb-2 movsi patterns caused a codesize regression with -Os in large functions. Fix this by using the literal pool offset of the 16-bit literal load so that the literal pool is dumped earlier, reducing the number of 32-bit literal loads.
