Multiple Simulators Link Failure on Head

Multiple Simulators Link Failure on Head

[Joel Sherrill]

Hi

Multiple targets fail to link with sim_addr_range_hit_p. The
targets are:

are you doing incremental builds ?  or did you build entirely from scratch ?  
some changes landed recently that would break incremental, so you should build 
the sim dir from scratch.

how exactly did you run configure ?  how about `make` ?

i build every sim target myself and run their testsuites before i push new sim 
commits ...

The build directory is removed and remade every time

Hmmm... h8300-rtems4.11 just built this morning.

Same build script. Not sure what happened. Let me do a build of all targets
again and see what happens this time.

sigh.. ghosts. :(

This looks to be an issue with the "make -j8".
I did it again with "-j8" and it failed. I did a simple "make clean all"
in that directory and it failed again.

I then changed my script to drop the -j8 and it built ok again.

My suspicion is something in the dependencies isn't 100% right
and there is a race condition. sim/common/cconfig.h is the same
in a tree built with -j1 vs -j8.

ok, i'll take a look.  i use -j4 everywhere myself, so most egregious errors 
shake out.

side note: could you avoid top posting ?

a high level note: it's not possible to race between common/ and other subdirs.  
the configure script explicitly runs configure for all subdirs first, and that 
is how config.h/cconfig.h get generated.  the common/ subdir otherwise does not 
produce any objects.

when it fails, can you attach the full build log ?

what gcc version are you using ?  there might be some misbehavior with the usage 
of extern inline.  i think the code base expects gnu_inline semantics but just 
uses "extern inline" directly.  maybe try including -fgnu89-inline in your 
CFLAGS and see if that helps ?

I am not in good position to send build logs or try the alternative CFLAGS
until another long build finishes.

But the idea of the gcc version sounds promising. I am building with a gcc
from near the head. The default version of C has changed to C11 and I
know that has caused a few odd issues with RTEMS. Maybe this has
impacted the the compilation of this method.

$ gcc --version
gcc (GCC) 5.0.0 20150211 (experimental)


I will try the suggestions as soon as I can.

I can confirm that lm32 and other targets built with the native
Fedora compiler.

$ gcc --version
gcc (GCC) 4.8.3 20140911 (Red Hat 4.8.3-7)

But failed with I switched to using the more recent native I
listed above.

I can provide a log if you want but that should be enough to
reproduce this.

ok, i guess i have to stop being lazy and get Gentoo's gcc-5 snapshots working 
again
