GNU style brace wrapping rules have been added to clang-format quite a while
ago.
http://llvm.org/viewvc/llvm-project/cfe/trunk/include/clang/Format/Format.h?revision=197138&view=markup
This simple patch proposes to use the built-in rules instead of the custom
brace rules.

Hi,
here there are a couple of rather straightforward improvements in the
second half of grokdeclarator plus a check_tag_decl change consistent
with the other existing case of multiple_types_p diagnostic. Tested

Thanks, Paolo.

-Og is documented as:
@option{-Og} should be the optimization
level of choice for the standard edit-compile-debug cycle, offering
a reasonable level of optimization while maintaining fast compilation
and a good debugging experience. It is a better choice than @option{-O0}
for producing
This patch adds a mode in which debug stmts and debug insns are
explicitly allowed to affect codegen. In particular:
- uses in debug binds become first-class uses, acting like uses in
executable code
- the use of DEBUG_EXPR_DECLs is banned. If we want to refer to
a temporary value in debug
This patch tries to make sure that, when optimising at -Og, the gimple
IL has appropriate debug information for the whole of a variable's scope.
It does the same for parameters in functions that always return (but still
misses cases in functions that don't return -- a TODO for later).
The idea is
This patch adds an option called -O1g, a half-way house between
-Og and -O1 in terms of both performance and debuggability.

I had a look through the patch and found just one small nit detailed
below.
The test was failing with false positive for the scan-assembler-not.
Firstly, we adjust the test conditions to use non-PIC code for Darwin.
Secondly, we have to account for out-of-line GPR restores which gives
a false positive on the scan-assembler-not. Lastly, we make the test a
bit more specifi
Emit __PPC__ (32b) and __PPC64__ (64bit) as per the other members
of the PowerPC port. Darwin has always emitted __ppc__ and __ppc64__
but some testcases rely on the upper case variants.
tested on powerpc-darwin9, applied to mainline.

Primarily, for compatibility with other members of the port.
Note, that we do not handle the longcall attribute, since longcall is not
required/used on current Darwin (supported only for legacy cases).

Darwin (unlike most of the members of the PowerPC port family)
defaults to signed chars, so the test was failing to compile with
a "mismatched parameters" error.

* gcc.target/powerpc/pr
This cannot pass for current Darwin, since it requires VSX and we don't have
any hardware supporting that. The “fix” is to add a dg-requires clause for
this.

Dear all,
the attached patch provides run-time checks for the bit manipulation
intrinsic functions (IBSET/IBCLR/BTEST/SHIFT[RLA]/ISHFT/ISHFTC).
I am using only one testcase whose purpose is mainly to verify that
there are no false positives, which I consider essential, and one
"failing" test at th

This patch to the Go frontend adds a new function go_debug and uses it
for debug messages.
GCC recently added a new warning -Wformat-diag which does a lot of
rigorous checks on GCC diagnostic messages. This produces a number of
unnecessary diagnostics on gofrontend diagnostic output, such as:

This patch to the Go frontend edits various error messages to avoid
-Wformat-diag warnings.

The attached patch cleans up a number of outstanding -Wformat-diag

With it applied, an x86_64-linux bootstrap shows just 79 unique

in the Go front-end that Ian is already dealing with. I
