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 -
o use this flag to set the personality routine of a function if it uses
exception handlinga
o also define FPC_USE_PSABIEH if this target flag is set
o set this target flag for darwin/x86-64 if the compiler is compiled with
-dllvm
git-svn-id: branches/debug_eh@40415 -
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
o prevents dependency cycles that can cause llvm codegen units to init
before the cpu variants, which is bad since the llvm versions have to
override the cpu variants in their init code (+ added checks in the
init code that they are in fact initialised later)
git-svn-id: branches/debug_eh@40410 -
exceptions for LLVM (except on Windows targets, since they (will) use
their own kind of exception handling)
o ensure we generate an external function symbol definition for such
personality functions on LLVM
git-svn-id: branches/debug_eh@40402 -
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
