The attached patch fixes an out of bound write to memory allocated with alloca() on the stack. This rarely ever happened because on one hand -fbounds-check needs to be enabled, and on the other hand alloca() used to allocate a few bytes extra most of the time so most of the time the excess write did no harm. gcc/fortran/ChangeLog: * trans-array.c (gfc_conv_array_ref): Fix allocation of diagnostic message (was too small). git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@238849 138bc75d-0d04-0410-961f-82ee72b054a4

2016-07-28On AArch64 the UXTB and UXTH instructions are aliases of UBFM,Wilco Dijkstra
which does a shift as part of its operation. An AND immediate is a simpler operation, and might be faster on some implementations, so it is better to emit this this instead of UBFM. Benchmarking showed no difference on implementations where UBFM has the same performance as AND, and minor speedups across several benchmarks on an implementation where UBFM is slower than AND.

2016-07-28This patchset improves zero extend costs and code generation.Kristina Martsenko
When zero extending a 32-bit register, we emit a "mov", but currently report the cost of the "mov" incorrectly. In terms of speed, we currently say the cost is that of an extend operation. But the cost of a "mov" is the cost of 1 instruction, so fix that. In terms of size, we currently say that the "mov" takes 0 instructions. Fix it by changing it to 1. Bootstrapped and tested on aarch64-none-elf. gcc/ * config/aarch64/aarch64.c (aarch64_rtx_costs): Fix cost of zero extend. git-svn-id: https://gcc.gnu.org/svn/gcc/trunk@238820 138bc75d-0d04-0410-961f-82ee72b054a4
