switching to Git - equivalent of svnmerge merge... [to merge trunk into MELT]?

in my life. What did I do wrong? What is the good way to merge the trunk back into my MELT branch using git? How can I ask git to ignore such "conflicts" (as svnmerge merge did)?

Re: Graduate research - how GCC compiles PTHREAD Mutex routines into x86/Linux Kernel 2.6 assembler

All the synchronisation magic happens inside them (in the libpthread.so library). You'll need to dig the source code of glibc/NPTL to understand the details. When your work is done, please publish it (in English) on some publicly accessible web page. I'm sure that would interest some peop

temporarily giving up using Git for GCC MELT

ce to face (and I don't have IRC) with my laptop. Regards. PS. By the way, git clone-ing the GCC git repository takes a lot of time from Europe. Perhaps having a daily tar ball of the result of that command available by ftp would be very nice -- Basile STARYNKEVITCH h

Perhaps a mailing list for plugins (& other GCC extensions) is needed?

gengtype state & srcdir???

Using GCC bugzilla for MELT specific bugs?

ld expect that to work, and it should work in MELT [but MELT has bugs]. That was a bug I easily corrected and committed svn rev 170818. Is GCC bugzilla the right place to report such bug totally specific to MELT? Regards. -- Basile STARYNKEVITCH http://starynkevitch.net

Re: [MELT] issue with the garbage collector

Serializing mixed gimple data from a plugin in LTO?

realmpfr.h not in PLUGIN_HEADERS?

Helo All, It seems that, since realmpfr.h is not listed in the PLUGIN_HEADERS in gcc/Makefile.in, it cannot be used from plugins. Is there a reason for that, or what? I feel that plugins need to know about and about the real_from_mpfr & mpfr_from_real functions. Cheers. -- Ba
