[openacc] clean up acc directive matching in fortran

I supposed I could have consolidated those two functions, but they are reasonably simple so I left them separate. Maybe a follow up patch can cons

This patch enhances the memory usage of object declarations initialized by a qualified array aggregate. Previously, as per RM 4.3(5), an anonymous object was created to capture the value of the array aggregate, effectively doubling the memory consumption. The changes above remove the anonymous obje

[Ada] Warn on buffer overrun with complex overlay

This change improves the warning issued for buffer overruns caused by overlays where the underlying object is too small, by taking into account the offset of the overlaid object from the first bit of the underlying object. The effect is visible on the following package: 1. with Interfaces; u

Actually, if possible, I would skip the "arm" part, because we plan to port Phoenix-RTOS for other platforms. It will be easier to do it once. 2016-06-16 10:52 GMT+02:00 Kyrill Tkachov : > > On 15/06/16 23:23, Jeff Law wrote: >> >> On 06/15/2016 08:21 AM, Jakub Sejdak wrote: >>> >>> Hello, >>> >>>
