Made all the changes. Modified the test case to check if the segment
splitting API is invoked.
Hi,
This patch adjusts the single target indirect call promotion heuristics.
(1) it uses bb counts (bb_all), instead of count "all" which only counts
the targets with the same modules as the caller.
(becaue __gcov_indirect_call_callee is file scope statics).
Using overall bb counts makes more sen
ok.

There was an earlier patch which touched g++.dg/parse/error1{1,2}.C:
r191712 | paolo | 2012-09-25 07:44:52 -0700 (Tue, 25 Sep 2012) | 15
This patch "removes" -fno-whole-file. (Actually, it turns it into "Ignore".)
Reasoning:
* -fwhole-file/-fno-whole-file was added in 4.5 to make the transition
easier; -fwhole-file is the default since 4.6.
* There are many wrong-code issues and probably also some ICEs with
-fno-whole file.
I saw only one test case fix patch from Paolo in trunk. Does this
patch include more local fixes?

OK. I know I can do that, but I would need to do it for every syscall since
every syscall can potentially clobber rbx.
Also, it is very strange that it is only one of the inlines the compiler
complains about. I have another inline (which uses rbx as input), but that
doesn't generate any error:

Hi,
currently byte swapped unformatted IO can be quite slow compared to
the same code with no byte swapping. There are two major reasons for
this:
1) The byte swapping code path resorts to transferring data element by

2) The function used

I just tried the patch, but it seems to produce some problems for me. The
other patch which used a 64-bit specific register (r15) instead of rbx was

When an anonymous class gets a linkage name from a typedef, we
recalculate its visibility; anonymous types have internal linkage, but
types with linkage names have external linkage and therefore can have
visibility. But we were forgetting to also recalculate the visibility
of any nested types,
