[[likely]] and [[unlikely]] are equivalent to the GNU hot/cold attributes, except that they can be applied to arbitrary statements as well as labels; this is most likely to be useful for marking if/else branches as likely or unlikely. Conveniently, PREDICT_EXPR fits the bill nicely as a representation. I also had to fix marking case labels as hot/cold, which didn't work before.

2018-11-16When running the testsuite on boards that can't report an error status ↵Matthew Malcomson3-0/+7
DejaGNU... When running the testsuite on boards that can't report an error status DejaGNU uses a special wrapper to print the exit code on stdout and parses stdout to find whether an execution failed or passed. In testcases that use "freopen (..., ..., stdout)" this special line is printed to the alternate location described in the freopen call and DejaGNU can't find the error code. This results in DejaGNU using a default return status of 2 and the test failing. This patch skips the two testcases that use freopen on stdout when testing a board that requires this wrapper. Testing done by running these two tests on arm-none-eabi cross build and observing that they are unsupported. gcc/testsuite/ChangeLog: 2018-11-16 Matthew Malcomson <matthew.malcomson@arm.com> * gcc.c-torture/execute/printf-2.c: Skip on wrapped boards. * gcc.c-torture/execute/user-printf.c: Likewise.

2018-11-15Handle vectors that don't fit in an integer.Andrew Stubbs2-4/+11
GCN vector sizes range between 64 and 512 bytes, none of which have correspondingly sized integer modes. This breaks a number of assumptions throughout the compiler, but I don't really want to create modes just for this purpose. Instead, this patch fixes up the cases that I've found, so far, such that the compiler tries something else, or fails to optimize, rather than just ICE. 2018-11-15 Andrew Stubbs <ams@codesourcery.com> Kwok Cheung Yeung <kcy@codesourcery.com> gcc/ * tree-vect-stmts.c (vectorizable_store): Don't ICE when int_mode_for_size fails.
