Hi, These new tests do not work well on arm-none-eabi and aarch64-none-elf. (as opposed to arm*linux* and aarch64*linux*) On arm-none-eabi, I see: /aci-gcc-fsf/builds/gcc-fsf-gccsrc/tools/arm-none-eabi/bin/ld: /aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-eabi/gcc3/gcc/testsuite/g++1/../../crtbegin.o: relocation R_ARM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC /aci-gcc-fsf/builds/gcc-fsf-gccsrc/obj-arm-none-eabi/gcc3/gcc/testsuite/g++1/../../crtbegin.o: error adding symbols: Bad value collect2: error: ld returned 1 exit status compiler exited with status 1 FAIL: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_0.C line 106) FAIL: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_0.C line 142) FAIL: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_0.C line 147) FAIL: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_1.C line 6) FAIL: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_2.C line 18) FAIL: g++.dg/lto/pr84805 cp_lto_pr84805_0.o-cp_lto_pr84805_2.o link, -O2 -fPIC -shared -flto On aarch64-none-elf, I see: /aci-gcc-fsf/builds/gcc-fsf-gccsrc/tools/aarch64-none-elf/bin/ld: /aci-gcc-fsf/builds/gcc-fsf-gccsrc/tools/lib/gcc/aarch64-none-elf/8.0.1/../../../../aarch64-none-elf/lib/librdimon.a(rdimon-syscalls.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against external symbol `_impure_ptr' can not be used when making a shared object; recompile with -fPIC PASS: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_0.C line 106) PASS: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_0.C line 142) PASS: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_0.C line 147) PASS: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_1.C line 6) PASS: g++.dg/lto/pr84805 (test for LTO warnings, pr84805_2.C line 18) FAIL: g++.dg/lto/pr84805 cp_lto_pr84805_0.o-cp_lto_pr84805_2.o link, -O2 -fPIC -shared -flto Christophe > -- > Eric Botcazou
