== This Week == * TCWG-619: * abe sysroot/libc issue While building chromium with development build of toolchain on arm-linux-gnueabihf, I get the following error: undefined reference to clock_gettime() Builds fine with release toolchain build. Symlinking libc in toolchain install directory to sysroots/arm-linux-gnueabihf appears to work (which is what --tarbin did).
* PR65778 - v8 fails to build with LTO - Resolved Invalid * PR65837 - target specific builtin not available - created a reduced test case - There's a weird issue: looks like for lto1, translation unit command line options, precede the default ones rather than overriding them. Assume test.c contains a neon intrinsic: arm-linux-gnueabihf-gcc -flto -c test.c -mfpu=neon arm-linux-gnueabihf-gcc -flto test.o results in target specific builtin not available, because both -mfpu=neon and -mfpu=vfpv3-d16 is passed and -mfpu=vfpv3-d16 overrides earlier -mfpu=neon Passing -mfpu=neon at link time correctly overrides -mfpu=vfpv3-d16. * PR6778 - ICE in varpool_node::get_constructor. - Looks like PR65776 appears due to same issue as well. - It appears error_mark_node gets streamed that causes ICE. - Triage went wrong, thought it was an error in typeck2.c:check_narrowing(). * PR49551 - The C front-end c/c-decl.c:merge_decls still incorrectly marks the variable as 'common' for the test-case: int x = 5; int x; However it's not reproducible anymore on trunk (maybe latent?) - I have an untested patch that resolves the issue in merge_decls(). * Issues - abe built native gcc on x8_64-unknown-linux-gnu fails to build code when passed -m32 option (bug 1508). * Misc - exams on 20th and 24th april. * Next week - Continue working on PR65837, PR65778 - Test patch for PR49551 _______________________________________________ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org https://lists.linaro.org/mailman/listinfo/linaro-toolchain
