Ok, my Fedora36 (ie, a default IEEE128 system) bootstrap using --with-long-double-format=ieee (and LIBDRUNTIME_ONLY=yes removed) completed with no errors and this is my gdc testsuite results, which looks pretty good to me (ie, vast majority of gdc tests pass). I can look into the few errors here, but after I look into the IBM128 default system build issue. === gdc tests === Running target unix FAIL: gdc.dg/Wbuiltin_declaration_mismatch1.d (test for warnings, line 10) FAIL: gdc.dg/torture/gdc309.d -O0 execution test FAIL: gdc.dg/torture/gdc309.d -O0 -g execution test FAIL: gdc.dg/torture/gdc309.d -O1 execution test FAIL: gdc.dg/torture/gdc309.d -O1 -g execution test FAIL: gdc.dg/torture/gdc309.d -O2 execution test FAIL: gdc.dg/torture/gdc309.d -O2 -g execution test FAIL: gdc.dg/torture/gdc309.d -O3 execution test FAIL: gdc.dg/torture/gdc309.d -O3 -g execution test FAIL: gdc.dg/torture/gdc309.d -Os execution test FAIL: gdc.dg/torture/gdc309.d -Os -g execution test UNRESOLVED: gdc.test/runnable/constfold.d compilation failed to produce executable UNRESOLVED: gdc.test/runnable/constfold.d -shared-libphobos compilation failed to produce executable FAIL: gdc.test/runnable/xtest46.d execution test FAIL: gdc.test/runnable/xtest46.d -shared-libphobos execution test FAIL: gdc.test/runnable/xtest46_gc.d execution test FAIL: gdc.test/runnable/xtest46_gc.d -shared-libphobos execution test === gdc Summary === # of expected passes 11442 # of unexpected failures 15 # of unresolved testcases 2 # of unsupported tests 442 /home/bergner/gcc/build/gcc-fsf-master-lang-D/gcc/gdc version 13.0.0 20220916 (experimental) (GCC)
