While such behavior makes little difference with generic setjmp-based exception handling, it becomes very inefficient as SEH-styled exception handling is being introduced. The new behavior is also Delphi-compatible. git-svn-id: http://svn.freepascal.org/svn/fpc/trunk@26180 3ad0048d-3df7-0310-abae-a5850022a9f2

* + support for nested procedural variables:jonas2010-07-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | o activate using {$modeswitch nestedprocvars} (compatible with all regular syntax modes, enabled by default for MacPas mode) o activating this mode switch changes the way the frame pointer is passed to nested routines into the same way that Delphi uses (always passed via the stack, and if necessary removed from the stack by the caller) -- Todo: possibly also allow using this parameter passing convention without enabling nested procvars, maybe even by default in Delphi mode, see mantis #9432 o both global and nested routines can be passed to/assigned to a nested procvar (and called via them). Note that converting global *procvars* to nested procvars is intentionally not supported, so that this functionality can also be implemented via compile-time generated trampolines if necessary (e.g. for LLVM or CIL backends as long as they don't support the aforementioned parameter passing convention) o a nested procvar can both be declared using a Mac/ISO Pascal style "inline" type declaration as a parameter type, or as a stand-alone type (in the latter case, add "is nested" at the end in analogy to "of object" for method pointers -- note that using variables of such a type is dangerous, because if you call them once the enclosing stack frame no longer exists on the stack, the results are undefined; this is however allowed for Metaware Pascal compatibility) git-svn-id: http://svn.freepascal.org/svn/fpc/branches/nestedprocvars@15656 3ad0048d-3df7-0310-abae-a5850022a9f2
