Unwinding past the unwind_rdi_rsi_handler function might require unwinding information, but I'm not sure if we have that when compiling with mingw? I thought this was not implemented yet. On the testbot it still passed, probably because it was luckily compiled to a simple leaf function. > + return ExceptionContinueSearch; > +} > + > +static const BYTE unwind_rdi_test_code[] = { > + 0x57, /* push %rdi */ > + 0x48, 0xc7, 0xc7, 0x55, 0x55, 0x55, 0x55, /* mov $0x55555555, %rdi */ > + 0xcc, /* int3 */ > + 0x48, 0x89, 0xf8, /* mov %rdi, %rax */ > + 0x5f, /* pop %rdi */ > + 0xc3, /* ret */ > +}; > + > +static const BYTE unwind_rsi_test_code[] = { > + 0x56, /* push %rsi */ > + 0x48, 0xc7, 0xc6, 0x33, 0x33, 0x33, 0x33, /* mov $0x33333333, %rsi */ > + 0xcc, /* int3 */ > + 0x48, 0x89, 0xf0, /* mov %rsi, %rax */ > + 0x5e, /* pop %rsi */ > + 0xc3, /* ret */ > +}; > + > +static void test_unwind_rdi_rsi(void) > +{ > + DWORD result; > + > + result = run_exception_test(unwind_rdi_rsi_handler, NULL, unwind_rdi_test_code, > + sizeof(unwind_rdi_test_code), 0); > + ok( result == 0x55555555, "expected %x, got %x\n", 0x55555555, result ); > + > + result = run_exception_test(unwind_rdi_rsi_handler, NULL, unwind_rsi_test_code, > + sizeof(unwind_rsi_test_code), 0); > + ok( result == 0x33333333, "expected %x, got %x\n", 0x33333333, result ); > +} > + > static DWORD WINAPI dr7_handler( EXCEPTION_RECORD *rec, ULONG64 frame, > CONTEXT *context, DISPATCHER_CONTEXT *dispatcher ) > { > @@ -2651,6 +2692,7 @@ START_TEST(exception) > test_virtual_unwind(); > test___C_specific_handler(); > test_restore_context(); > + test_unwind_rdi_rsi(); > > if (pRtlAddFunctionTable && pRtlDeleteFunctionTable && pRtlInstallFunctionTableCallback && pRtlLookupFunctionEntry) > test_dynamic_unwind(); >

We already have the signal_i386 code for an example how to do it, and other functions like NtGetContextThread also support querying the debug registers (even on x86_64). Best regards, Sebastian

Re: [3/3] wined3d: Upload textures if NO_DIRTY_UPDATE flag is set when locking dynamic textures.

Hi, While running your changed tests on Windows, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check? Full results can be found at https://testbot.winehq.org/JobDetails.pl?Key=28316 Your paranoid android. === w1064 (32 bit visual) === visual.c:7989: Test failed: Got unexpected color 0x00007580 for quad 2 (different colors). visual.c:8093: Test failed: Got unexpected color 0x00ff0000 for no color attribute test.

In d3d11 these are called "D3D11_BLEND_INV_SRC1_ALPHA", etc.
