Hi! When linking with -static-lib{a,t,l,ub}san -fsanitize=whatever, we link -l{a,t,l,ub}san statically into the binary and add the set of libraries needed by the lib{a,t,l,ub}san.a afterwards (-lpthread, -ldl etc.). When doing -static -fsanitize=whatever link, we link the sanitizer library statically too due to -static, so we need to also ensure we append the libraries needed by that.
Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2018-02-09 Jakub Jelinek <ja...@redhat.com> PR sanitizer/84285 * gcc.c (STATIC_LIBASAN_LIBS, STATIC_LIBTSAN_LIBS, STATIC_LIBLSAN_LIBS, STATIC_LIBUBSAN_LIBS): Handle -static like -static-lib*san. --- gcc/gcc.c.jj 2018-01-09 09:01:39.017042679 +0100 +++ gcc/gcc.c 2018-02-08 15:56:13.361836160 +0100 @@ -684,7 +684,7 @@ proper position among the other output f #ifndef LIBASAN_SPEC #define STATIC_LIBASAN_LIBS \ - " %{static-libasan:%:include(libsanitizer.spec)%(link_libasan)}" + " %{static-libasan|static:%:include(libsanitizer.spec)%(link_libasan)}" #ifdef LIBASAN_EARLY_SPEC #define LIBASAN_SPEC STATIC_LIBASAN_LIBS #elif defined(HAVE_LD_STATIC_DYNAMIC) @@ -702,7 +702,7 @@ proper position among the other output f #ifndef LIBTSAN_SPEC #define STATIC_LIBTSAN_LIBS \ - " %{static-libtsan:%:include(libsanitizer.spec)%(link_libtsan)}" + " %{static-libtsan|static:%:include(libsanitizer.spec)%(link_libtsan)}" #ifdef LIBTSAN_EARLY_SPEC #define LIBTSAN_SPEC STATIC_LIBTSAN_LIBS #elif defined(HAVE_LD_STATIC_DYNAMIC) @@ -720,7 +720,7 @@ proper position among the other output f #ifndef LIBLSAN_SPEC #define STATIC_LIBLSAN_LIBS \ - " %{static-liblsan:%:include(libsanitizer.spec)%(link_liblsan)}" + " %{static-liblsan|static:%:include(libsanitizer.spec)%(link_liblsan)}" #ifdef LIBLSAN_EARLY_SPEC #define LIBLSAN_SPEC STATIC_LIBLSAN_LIBS #elif defined(HAVE_LD_STATIC_DYNAMIC) @@ -738,7 +738,7 @@ proper position among the other output f #ifndef LIBUBSAN_SPEC #define STATIC_LIBUBSAN_LIBS \ - " %{static-libubsan:%:include(libsanitizer.spec)%(link_libubsan)}" + " %{static-libubsan|static:%:include(libsanitizer.spec)%(link_libubsan)}" #ifdef HAVE_LD_STATIC_DYNAMIC #define LIBUBSAN_SPEC "%{static-libubsan:" LD_STATIC_OPTION \ "} -lubsan %{static-libubsan:" LD_DYNAMIC_OPTION "}" \ Jakub
