2017-10-04C: underline parameters in mismatching function callsDavid Malcolm9-42/+206
In r253096 ("C++: underline parameters in mismatching function calls" aka 5d78d423a5f7a1d135c7bb678e82007678d1313c https://gcc.gnu.org/ml/gcc-patches/2017-09/msg01546.html ) I updated the C++ FE's handling of mismatched types in function calls so that it underlines the pertinent param of the callee, rather than just the function name. The following patch does the same for the C frontend. Given e.g. this type mismatch: extern int callee (int one, const char *two, float three); int caller (int first, int second, float third) { return callee (first, second, third); } the C FE currently emits (trunk): test.c: In function 'caller': test.c:5:25: warning: passing argument 2 of 'callee' makes pointer from integer without a cast [-Wint-conversion] return callee (first, second, third); ^~~~~~ test.c:1:12: note: expected 'const char *' but argument is of type 'int' extern int callee (int one, const char *two, float three); ^~~~~~ whereas with this patch the note underlines the pertinent param of the callee: test.c: In function 'caller': test.c:5:25: warning: passing argument 2 of 'callee' makes pointer from integer without a cast [-Wint-conversion] return callee (first, second, third); ^~~~~~ test.c:1:41: note: expected 'const char *' but argument is of type 'int' extern int callee (int one, const char *two, float three); ~~~~~~~~~~~~^~~ making the problem more obvious to the user. As with the C++ patch, the patch: (a) updates the locations of the params to cover the range of all of their tokens, putting the caret on the first character of the param name (if present), otherwise at the start of the first token (doing so requires adding a last_token_location to the c_parser, so we can determine the location of the last consumed token). (b) updates the "note" to use the param location, rather than the fndecl location gcc/c/ChangeLog: * c-decl.c (push_parm_decl): Store c_parm's location into the PARAM_DECL. (build_c_parm): Add "loc" param and store it within the c_parm. * c-parser.c (struct c_parser): Add "last_token_location" field.

2017-10-04Fix PR82396: qsort comparator non-negative on sorted outputWilco Dijkstra3-97/+24
r253236 broke AArch64 bootstrap. Earlier revision r253071 changed scheduling behaviour on AArch64 as autopref scheduling no longer checks the base. This patch fixes the bootstrap failure and cleans up autopref scheduling. The code is greatly simplified. Sort accesses on the offset first, and only if the offsets are the same fall back to other comparisons in rank_for_schedule. This doesn't at all restore the original behaviour since we no longer compare the base address, but it now defines a total sorting order. More work will be required to improve the sorting so that only loads/stores with the same base are affected. gcc/ PR rtl-optimization/82396 * haifa-sched.c (autopref_multipass_init): Simplify initialization.

2017-10-03simplify-rtx: Remove non-simplifying simplification (PR77729)Segher Boessenkool2-25/+6
If we have (X&C1)|C2 simplify_binary_operation_1 makes C1 as small as possible. This makes worse code in common cases like when the AND with C1 is from a zero-extension. This patch fixes it by removing this transformation (twice). PR rtl-optimization/77729 * simplify-rtx.c (simplify_binary_operation_1): Delete the (X&C1)|C2 to (X&(C1&~C2))|C2 transformations.
