[Ada] Preliminary work to avoid full pathnames in ALI files

Normally, ALI files refer to source files using simple names. This allows files to be moved around without disturbing things (causing extra recompilations, etc). However, for configuration files, the full pathname is stored. This patch preparates the code base to store the simple name in this case.

C++ PATCH to add -Winit-list-lifetime (47445, 67711, 48562, 85873)

There have been several bug reports either being surprised that the backing array for an initializer_list went away unexpectedly, or asking for a warning about such situations. This patch adds a new warning flag -Winit-list-lifetime, on by default, to warn about * returning an automatic initializ

[PATCH 00/10] RFC: Prototype of compiler-assisted performance analysis

I want to provide more "actionable" information on how GCC optimizes code, both for us (GCC developers), and for advanced end-users. For us, I want to make it easier to get a sense of how an optimization can be improved (bug-fixing). For end-users, I want to make it easier to figure out which comm

[PATCH 01/10] Convert dump and optgroup flags to enums

The dump machinery uses "int" in a few places, for two different sets of bitmasks. This patch makes things more self-documenting and type-safe by using a new pair of enums: one for the dump_flags_t and another for the optgroup_flags. This requires adding some overloaded bit operations to the enum

[PATCH 02/10] Add JSON implementation

This patch is the JSON patch I posted last year; it adds support to gcc for reading and writing JSON, based on DOM-like trees of json::value instances. This is overkill for what's needed by the rest of the patch kit (which just needs to be able to write JSON), but this code already existed, so I'm

Re: [C++ PATCH] Do not warn about zero-as-null when NULL is used.

Another round. The other occurrence of maybe_warn_zero_as_null_pointer_constant in typeck.c seems superfluous. The one in cvt.c seems necessary for cpp0x/Wzero-as-null* tests. It seems like cp_build_binary_op is far more suited to check the EQ_EXPR/NE_EXPR cases than conversion_null_warnings is. T
