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
git-svn-id: branches/debug_eh@40401 -
o use this to handle non-power-of-two-sized parameters for llvm
o no general support in the parser/code generator, so don't expose
git-svn-id: trunk@40398 -
so that they can still be freed after the reference has been changed
(e.g. in case of array indexing or record field accesses) (mantis #33628)
git-svn-id: trunk@38814 -
indirectly depends on llvmpara and hence is initialised after instead
of before it (since llvmpara should override cpupara in its init code)
git-svn-id: trunk@36264 -
+ support for LLVM nil tai operands (will be used for terminating a daisy
chain of catch/filter clauses of landingpads): don't try to write it
git-svn-id: trunk@35160 -
as list of defs to be stored in the record, so we don't need to create and
free a class instance every time we call this routine
git-svn-id: trunk@35155 -
TP-style object to another and the sizes differ, at least if they are
related
* restructured and commented the LLVM type conversion checks
git-svn-id: trunk@35137 -
floating point type to currency, as fptosui is defined as always rounding
to zero while on other platforms we use the FPU's current rounding mode
(fixes webtbs/tw21449 for LLVM, and also webtbs/tw24197 because LLVM's
code generated for fptosui temporarily changes the FPU control word so
it rounds to zero and also to disable FPU exceptions)
git-svn-id: trunk@35061 -
add such symbols to the pseudo-arrays llvm.compiler.used or llvm.used
depending on their nature (fixes compiling Objective-C programs with
optimization, and keeps the FPC ident in the linked binary)
git-svn-id: trunk@35041 -
typed constant does not match the equivalent LLVM definition (it's only
used to check whether any emitted data's type differs from the LLVM
definition's field types)
o fixed a potential out-of-bounds access related to this: the index of the
equivalent LLVM field kept getting increased and at some point we checked
whether the current emitted data's type was different from the LLVM field
type without verifying first that the LLVM equivalent field index was not
yet beyond the number of LLVM equivalent fields
git-svn-id: trunk@35018 -
the buffer in the type, and support typecasting the typed file to a
different size (needed to be able to pass it to the compiler helpers that
expected a "TypedFile", whose buffer is 0 bytes and which hence will
always have a smaller size than the original type) (fixes test/tisoext1)
git-svn-id: trunk@35017 -
o separate information for reading and writing, because e.g. in a
try-block, only the writes to local variables and parameters are
volatile (they have to be committed immediately in case the next
instruction causes an exception)
o for now, only references to absolute memory addresses are marked
as volatile
o the volatily information is (should be) properly maintained throughout
all code generators for all archictures with this patch
o no optimizers or other compiler infrastructure uses the volatility
information yet
o this functionality is not (yet) exposed at the language level, it
is only for internal code generator use right now
git-svn-id: trunk@34996 -
stored in more than one register (has a self and a code pointer), instead
of assuming it always occupies more than one register if the original
procdef had a self pointer (can be different when getting the address
of a static class procedure)
