Fixes these testsuite fails on Windows: FAIL: gdb.base/callfuncs.exp: p t_float_complex_values(fc1, fc2) FAIL: gdb.base/callfuncs.exp: p t_float_complex_many_args(fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4) FAIL: gdb.base/callfuncs.exp: noproto: p t_float_complex_values(fc1, fc2) FAIL: gdb.base/callfuncs.exp: noproto: p t_float_complex_many_args(fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4) FAIL: gdb.base/call-sc.exp: p/c fun(); call call-sc-tld FAIL: gdb.base/call-sc.exp: advance to fun for return; return call-sc-tld FAIL: gdb.base/call-sc.exp: zed L for return; return call-sc-tld FAIL: gdb.base/call-sc.exp: return foo; return call-sc-tld FAIL: gdb.base/call-sc.exp: return foo; synchronize pc to main() for 'call-sc-tld' FAIL: gdb.base/call-sc.exp: return foo; synchronize pc to main() for 'call-sc-tld' FAIL: gdb.base/call-sc.exp: advance to fun for finish; return call-sc-tld FAIL: gdb.base/call-sc.exp: zed L for finish; return call-sc-tld FAIL: gdb.base/call-sc.exp: finish foo; return call-sc-tld (the program is no longer running) FAIL: gdb.base/call-sc.exp: value foo finished; return call-sc-tld For function arguments (callfuncs.exp), only TYPE_CODE_COMPLEX was missing in the types passed via integer registers. For return values, there were a lot more issues: - TYPE_CODE_DECFLOAT is NOT returned via XMM0. - long double is NOT returned via XMM0. - but __int128 IS returned via XMM0. - the comments for TYPE_CODE_FLT state that __m128, __m128i and __m128d are returned by XMM0, and this is correct, but it doesn't actually check for them, because they are TYPE_CODE_ARRAY with TYPE_VECTOR So I had to add TYPE_CODE_DECFLOAT to the arguments passed via XMM register, but I had to remove it from the values returned via XMM0 register. gdb/ChangeLog: 2020-10-05 Hannes Domani <ssbssa@yahoo.de> * amd64-windows-tdep.c (amd64_windows_passed_by_integer_register): Add TYPE_CODE_COMPLEX. (amd64_windows_return_value): Fix types returned via XMM0. gdb/testsuite/ChangeLog: 2020-10-05 Hannes Domani <ssbssa@yahoo.de> * gdb.base/call-sc.c: Fix return struct on stack test case. * gdb.base/call-sc.exp: Likewise.
