For each translation unit, a CTF container (ctf_container_t) is used to
keep the CTF debug info.
- ctfout.c hosts the compiler facing routines for CTF generation and emission.
- ctfcreate.c contains the CTF format specific CTF creation routines.
- ctfutils.c contains helper routines for CTF creati

-gtLEVEL is used to request CTF debug information and also to specify how much
CTF debug information.
gcc/ChangeLog:
* common.opt: Add CTF debug info options.
* doc/invoke.texi: Document the CTF debug info options.
* flag-types.h (enum ctf_debug_info_levels): New enum.
Hello,
This patch series adds support for CTF generation in GCC.
[Changes from V4]
1. Patch 4 brings in a number of bug fixes and enhancements. Few of them are:
- Use DECL_UID () instead of htab_hash_pointer () for _DECL
- Handle boolean and zero-sized bitfields
- Do not inform () when

[dcl.type.auto.deduct]/5 "If the placeholder-type-specifier is of the
form type-constraintopt decltype(auto), T shall be the placeholder alone."
So, only plain decltype(auto) is allowed. But we aren't diagnosing it in
function declarations, because do_auto_deduction is never called for those.

Approved.
As in: Approved by the steering committed assuming the patchset passes
technical review. :-)
Thanks for w
Even on recent processors, integer division is relatively expensive.
The current implementation of std::uniform_int_distribution typically
requires two divisions by invocation:
// downscaling
const __uctype __uerange = __urange + 1; // __urange can be zero
const __uctype _

We've already beaten this topic to death, so let's put a final nail in
the coffin:
__to_chars_10_impl is quite fast. According to the IACA the main loop
takes only 6.0 cycles, the whole function with one iteration takes
10.0 cycles. Replacing the __first[pos] and __first[pos - 1] with
__first[0]
