Hi!
In r10-1938-g460bf043c8266dd080308f4783137aee0d0f862c *testdi_1 has been
changed, so that if the mask has upper 32-bits 0 and then at least one bit
set, it requires CCZmode rather than CCNOmode, because in that case it uses
testl instruction rather than testq and so the SF flag wouldn't respec

The filesystem::path::operator+= and filesystem::path::concat functions
operate directly on the native format of the path and so can cause a
path to mutate to a completely different type.

This patch adds a new flag -fconcepts-diagnostics-depth to the C++ frontend

The first patch tries to avoid changing our current default diagnostics. But
for the sake of consistency we arguably should also respect

Hi,
There is no single PC offset that is correct given CPUs may use different
offsets.
GCC may also schedule the instruction that stores the PC. This feature used to
work on early Arms but is no longer functional or useful today, so the best way
forward is to remove it altogether. There are many

Hi.
With change of -fno-common default for GCC 10 we're facing serious
problem with LTO where one can't distinguish in between global symbols
and variables based on the output of nm:
https://sourceware.org/bugzilla/show_bug.cgi?id=25355
$ cat nm.c
char nm_test_var;
$ gcc-9 nm.c -c -fno-common
$
Forwarding to public list.
