Hello,
this patch adds a new option -nolibc to supress -lc in the link command.
This refines -nostdlib/-nostartfiles/nodefaultlibs, so that it is
possible to link with libgcc but without libc.
Our main use case is for embedded targets when we use the GNAT compiler
without an installed libc.
Hi.
Following simple patch adds support for dumping of BBs when it's a BB
that contains a label. That makes it easier for debugging as one can
find destination for an edge in dump file.
Sample, before:
foo (int a)
{
int D.1821;
int _1;
int _4;
int _5;
[0.00%] [count: INV]:

To recap, -Wmultistatement-macros warns for code like
#define FOO y++; z++
if (i)
FOO;
if FOO expands to multiple statements not wrapped in {}. It tracks the
location of the guard (if), the location of the body of the conditional
(y++) and the location of the following statement (z++).

Better with the patch file...
Sorry. The Resend did not add the joint file I added with first message (in
HTML format, refused).
Hope it's OK now.

In GCC 7, the rs6000 port made the switch to using LRA over reload by
default. We kept the ability of using reload in case there was an LRA
issue. We have squashed all known rs6000 specific LRA bugs and now is
the time to remove the ability to use reload from GCC 8/rs6000.
The first patch replac

This patch makes the -mlra option a nop while disallowing -mno-lra.
It also removes the target bit mask and its usage.
Finally, this patch updates the testsuite by removing all usage of
the -mlra and -mno-lra options.
This passed bootstrap and regtesting with no regressions, ok for trunk?

This patch removes reload specific code from the rs6000 port made possible
by the elimination of the usage of the -mno-lra option.

Hi Ian, David,
On AIX, that is more complicated...
We have to use -static-libgo when building the libgo tests. Because AIX does
not work like Linux does and because the Go libgo tests are done by duplicating
several .go files of libgo packages that already appear in the libgo.a

It appears to work for me: I can generate a simple no-op executable and link it
with multilib. I don't know anything about RTEMS, so I'm just going to trust
it'll actually work :). We're not going to have bandwidth to test this, but if
you're interested there's some support for running the GCC te
