http://d.puremagic.com/issues/show_bug.cgi?id=1829 Summary: Inline assembler cannot get label addresses Product: D Version: 1.026 Platform: PC OS/Version: Windows Status: NEW Severity: major Priority: P2 Component: DMD AssignedTo: bugzilla digitalmars.com ReportedBy: burton-radons shaw.ca The inline assembler can't read label addresses. This makes it impossible to do certain low-level tasks. For example, this code is rejected: asm { label: push label; } With the error "undefined identifier 'label'". Given that it's blocking me, I've given this major severity. --

http://d.puremagic.com/issues/show_bug.cgi?id=1829 bugzilla digitalmars.com changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|major |minor Here's how to push a label on the stack: call L1 ; L1: Because the workaround is straightforward, I'm going to lower the priority. It's not likely to get fixed soon, as it's been a limitation of the inline assembler for 15 years. :-( --

http://d.puremagic.com/issues/show_bug.cgi?id=1829 That's a bizarre workaround. If I needed to get the address of a block of code (such as an exception handler) I'd have to do something like this: call grab_exception_handler_address; // Grab the exception handler and put it in EAX. ... grab_exception_handler_address: // Try to make it as thread-safe as possible to tell the exception handler we're pulling an address. mov EAX, 0xDEADBEEF; mov ECX, 0xBEEFDEAD; mov EDX, 0x12345678; call exception_handler; mov EAX, [ESP]; ret; exception_handler: test EAX, 0xDEADBEEF; jne exception_handler_body; test ECX, 0xBEEFDEAD; jne exception_handler_body; test EDX, 0x12345678; jne exception_handler_body; // Pulling an address, do nothing. ret; exception_handler_body: // Actually calling the exception. I don't know that I'd call that "straightforward", but I understand you being limited by your code. --

It's not a biggie if final switch can generate branchless jump-tables. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
