I'd like to build www/firefox with both DTrace and LTO support. Both Clang and GCC emit code that dtrace(1) doesn't understand.
$ cat main.c #include <sys/sdt.h> #include <unistd.h> int main() { DTRACE_PROBE(test, foo); sleep(300); return 0; } $ cat test.d provider test { probe foo(); }; $ clang50 -flto -c main.c $ dtrace -G -s test.d main.o dtrace: failed to link script test: invalid file type: main.o $ file main.o main.o: LLVM IR bitcode $ gcc7 -flto -c main.c $ dtrace -G -s test.d main.o dtrace: failed to link script test: No probe sites found for declared provider $ file main.o main.o: ELF 64-bit LSB relocatable, x86-64, version 1 (FreeBSD), not stripped -- $ uname -a FreeBSD ... 12.0-CURRENT #0 r325899M ... amd64 _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
