* nested exception handling statments in one procedure need to be fixed
* clean up, finally factor out tcgprocinfo from psub at least
* extensive testing
git-svn-id: branches/debug_eh@41289 -
texceptionstatehandler class + llvm overrides
+ added FPC_DummyPotentialRaise routine that gets called at the begin and end
of try-blocks to be able to catch hardware exceptions to a limited extent
with LLVM
git-svn-id: branches/debug_eh@40418 -
the parent exception frame (-> pop current exception label, invoke/call
reraise, push current exception label again)
git-svn-id: branches/debug_eh@40417 -
referred by invoke instructions in exception catching blocks
o for now we won't actually use ABI-compliant exception handling, but we
need invoke/landingpad combinations for LLVM's control flow analyses to
correctly handle code involving exception handling
git-svn-id: branches/debug_eh@40401 -
o ensure that the label's local "jumpbuf" variable gets moved to the
parentfpstruct soon enough
o don't generate global symbols for interprocedural labels: they're not
necessary if they are only used via setjmp/longjmp (all references are
local in that case), and if they are referenced via an assembler block
then we'll have to handle them by passing a blockaddress() expression
as parameter to that assembler block (which does not require a global
symbol, but which is not yet implemented)
