Hi, I tried building GMP 6.1.0 on ARMv8 machine (aarch64): wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-6.1.0.tar.bz2 bunzip2 gmp-6.1.0.tar.bz2 tar xvf gmp-6.1.0.tar cd gmp-6.1.0 ./configure --disable-shared --enable-static --prefix=/tmp/gcc make && make check && make install
GCC: With gcc 11.4.0 and -O2 one of the tests fails: ../test-driver: line 107: 118960 Aborted (core dumped) "$@" > $log_file 2>&1 FAIL: t-count_zeros And with a bit of investigation: Program received signal SIGABRT, Aborted. __pthread_kill_implementation (threadid=281474842459776, signo=signo@entry=6, no_tid=no_tid@entry=0) at ./nptl/pthread_kill.c:44 44 ./nptl/pthread_kill.c: No such file or directory. (gdb) When building with: gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0 Next, I tried with gcc -O0, and then the make check ends normally. I repeated it with GMP 6.3.0 (got with ). CLANG: To rule out, issues form gcc, I tried clang too. I build GMP 6.1.0 with clang 14 and -O2 and then one of the tests failed: ../../test-driver: line 107: 141274 Aborted (core dumped) "$@" > $log_file 2>&1 FAIL: t-sqrlo With this version: Ubuntu clang version 14.0.0-1ubuntu1.1 Target: aarch64-unknown-linux-gnu Thread model: posix InstalledDir: /usr/bin the log shows: === cat tests/mpn/test-suite.log ============================================ GNU MP 6.1.0: tests/mpn/test-suite.log ============================================ # TOTAL: 46 # PASS: 45 # SKIP: 0 # XFAIL: 0 # FAIL: 1 # XPASS: 0 # ERROR: 0 .. contents:: :depth: 2 FAIL: t-sqrlo ============= ERROR in test 0, n = 12before scratch:0 keep: FFFF00000000 after scratch:0 keep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t-sqrlo (exit status: 134) === Then I tried to build GMP 6.3.0 with clang, and it normally ends (compilation and check) but skips one test: SKIP: t-addaddmul I think, as it is not the latest version, maybe it is not super interesting to fix this issue in older version of GMP, but maybe it is worth adding it as known issue in ARMv8, with the solution that is, to build it with -O0 or get newer version if possible.
