int64_t definition conflict on Aarch64

by Riku Voipio

Hi, The following code fails to build with OE Aarch64 toolchain with current kernel headers. While ugly, the code is a reduced testcase from fuse build failure ( https://bugs.launchpad.net/linaro-oe/+bug/1087757 ) and the same fuse code compiles on all other architectures. Before I send a workaround for upstream, I'd like to know how we can end up with different definitions for int64_t when that happens on no other architectures - something wrong with the generic kernel headers? Testcase: #include <sys/types.h> #define __s64 int64_t #include <signal.h> int main(int argc, char **argv) { int64_t x=4; return x; } Failure: /data/oe/build/tmp-eglibc/sysroots/x86_64-linux/usr/bin/aarch64-oe-linux/aarch64-oe-linux-gcc -save-temps --sysroot=/data/oe/build/tmp-eglibc/sysroots/genericarmv8 -o test test.c In file included from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/types.h:7:0, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/types.h:1, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/linux/types.h:4, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm/sigcontext.h:19, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/bits/sigcontext.h:27, from /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/signal.h:338, from test.c:4: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/asm-generic/int-ll64.h:29:44: error: conflicting types for 'int64_t' In file included from test.c:2:0: /data/oe/build/tmp-eglibc/sysroots/genericarmv8/usr/include/sys/types.h:197:13: note: previous declaration of 'int64_t' was here

[Activity] Week 52

by Zhenqiang Chen

Summary: * Follow-up shrink-up and branch cost related work. * Investigate "MSR FPEXC, r2" assemble fail issues. Details: 1. RM toolchain related work. 2. Investigate "MSR FPEXC, r2" assemble fail issues. * According to Reference Manual, should use VMSR/VMRS to access FPEXC register other than MSR/MRS. * Binutils 2.23.1 or later had enhanced VMRS/VMSR to accept FPEXC register. 3. Rebase and test the shrink-wrap patches. 4. Read codes about impact of branch-cost. Plan: * Follow up the shrink-wrap and branch cost related work. Planed leaves: * Jan. 1-3, 2013 Best Regards! -Zhenqiang

by Christophe Lyon

== Progress == * 64-bits ops in Neon: re-posted patch after a bit of cleanup requested by upstream. Investigated Fortran regression: confirmed unrelated to this patched, and fixed upstream. * disable-peeling: launched jobs under cbuild to perform initial benchmarking * builtin_bswap16 backport to linaro-4.7: almost OK, missing some pending validation results. * cbuild: investigated some reporting problems which were slowing down the branch review process. == Next == * handle 64-bits bitops in Neon feedback from upstream if any * finish builtin_bswap16 backport * benchmark with vectorizer cost model enabled with its default configuration == Future == Back on January 7th, after the end of the world.

Re: [Merge] lp:~brice-dobry/gcc-linaro/fma into lp:gcc-linaro

If you look at upstream SVN GCC and do svn propget svn:ignore you get a long list of files that SVN is set up to ignore. And whilst there isn't a .gitignore other upstream projects which have git mirrors do put a .gitignore in place (see GDB for instance). I think having a .bzrignore which is a copy of the svn:ignore set up (and the defaults that SVN ignores but aren't on bzr's list) would be valid in the repo. Although as I said in the original thread - let's do this when we branch 4.8 and not to the historic branches.
