2018-07-19[PATCH, GCC, AARCH64] Add support for +profile extensionAndre Vieira6-0/+24
This patch adds support for the Statistical Profiling Extension (SPE) on AArch64. Even though the compiler will not generate code any differently given this extension, it will need to pass it on to the assembler in order to let it correctly assemble inline asm containing accesses to the extension's system registers. The same applies when using the preprocessor on an assembly file as this first must pass through cc1. I left the hwcaps string for SPE empty as the kernel does not define a feature string for this extension. The current effect of this is that driver will disable profile feature bit in GCC. This is OK though because we don't, nor do we ever, enable this feature bit, as codegen is not affect by the SPE support and more importantly the driver will still pass the extension down to the assembler regardless. gcc/ChangeLog 2018-07-19 Andre Vieira <andre.simoesdiasvieira@arm.com> * config/aarch64/aarch64-option-extensions.def: New entry for profile extension. * config/aarch64/aarch64.h (AARCH64_FL_PROFILE): New. * doc/invoke.texi (aarch64-feature-modifiers): New entry for profile extension. gcc/testsuite/ChangeLog 2018-07-19 Andre Vieira <andre.simoesdiasvieira@arm.com> * gcc.target/aarch64/profile.c: New test.

2018-07-17compiler: don't set btype_ too early for alias typeIan Lance Taylor2-3/+5
CL 123362 introduced a bug in creating alias type's backend representation. A type's btype_ should not be set before named types are converted if it is a placeholder.

2018-07-17compiler: connect the concrete type and the placeholder for circular typesIan Lance Taylor3-24/+5
Previously, when creating the backend representation of a circular type, we resolve the placeholder to a circular_pointer_type. The backend doesn't know what the concrete type is. This CL changes it to resolve the placeholder to the concrete type instead, so the backend may have better knowledge of the concrete type.
