Bug #: 13255 Summary: Wrong `local symbol is referenced by DSO' warnings on Solaris Product: binutils Version: 2.22 Status: NEW Severity: critical Priority: P1 Component: ld AssignedTo: unassig...@sourceware.org ReportedBy: r...@techfak.uni-bielefeld.de Classification: Unclassified Host: i386-pc-solaris2.11 Target: i386-pc-solaris2.11 Build: i386-pc-solaris2.11 I've just tried gcc mainline with binutils 2.21.90 on Solaris 11/x86. Apart from PR ld/13254, I've got many gcc testsuite failures like the following: FAIL: gcc.dg/special/gcsec-1.c (test for excess errors) Excess errors: /vol/gcc/bin/gld-2.21.90: . WARNING: gcc.dg/special/gcsec-1.c compilation failed to produce executable Running test manually yields > /vol/gcc/obj/gcc-4.7.0-20110930/11-gcc-gas-gld22190/gcc/xgcc > -B/vol/gcc/obj/gcc-4.7.0-20110930/11-gcc-gas-gld22190/gcc/ > /vol/gcc/src/hg/trunk/solaris/gcc/testsuite/gcc.dg/special/gcsec-1.c > -ffunction-sections -fdata-sections -Wl,--gc-sections -lm -o ./gcsec-1.exe /vol/gcc/bin/gld-2.21.90: ./gcsec-1.exe: local symbol `__flt_rounds@@SYSVABI_1.3' in /lib/libc.so is referenced by DSO /vol/gcc/bin/gld-2.21.90: final link failed: Bad value collect2: error: ld returned 1 exit status so it seems most of the error message is stripped by the gcc testsuite framework. > gld-2.21.90 --eh-frame-hdr -m elf_i386_sol2 -Y P,/usr/ccs/lib:/lib:/usr/lib > -Qy -o ./gcsec-1.exe /usr/lib/crt1.o /usr/lib/crti.o /usr/lib/values-Xa.o > /vol/gcc/obj/gcc-4.7.0-20110930/11-gcc-gas-gld22190/gcc/crtbegin.o > -L/vol/gcc/obj/gcc-4.7.0-20110930/11-gcc-gas-gld22190/gcc gcsec-1.o > --gc-sections -lm -lgcc -lgcc_eh -lc -lgcc -lgcc_eh > /vol/gcc/obj/gcc-4.7.0-20110930/11-gcc-gas-gld22190/gcc/crtend.o > /usr/lib/crtn.o gld-2.21.90: ./gcsec-1.exe: local symbol `__flt_rounds@@SYSVABI_1.3' in /lib/libc.so is referenced by DSO gld-2.21.90: final link failed: Bad value The main problem is that the error is wrong: __flt_rounds *isn't* a local symbol: ro@fuego 185 > nm /lib/libc.so|grep __flt_rounds [8262] | 1496252| 4|OBJT |GLOB |0 |29 |__flt_rounds [1237] | 0| 0|FILE |LOCL |0 |ABS |__flt_rounds.c It is referenced in libm.so: /lib/libm.so: [2411] | 0| 0|OBJT |GLOB |0 |UNDEF |__flt_rounds /lib/libc.so: [8262] | 1496252| 4|OBJT |GLOB |0 |29 |__flt_rounds /lib/libc.so: [1237] | 0| 0|FILE |LOCL |0 |ABS |__flt_rounds.c Apart from that, even if it were correct, the error message is pretty useless: which DSO does it reference? I fear this is a showstopper bug: it renders gld complete useless on Solaris. I've only tried Solaris 11 so far, but expect that there's no difference on older releases.
