the upper 7 bits of the boolean, while other platforms take it into
account (even though they're technically always required to be 0, and
the value is undefined if they're not)

even when it's the same as the stack alignment (it can also refer to the
alignment of the data pointed to by pointer parameters)
git-svn-id: branches/debug_eh@41729 -
store tai in them
+ support for direct symbol parameters to llvm routines (without first
loading them into register)
o needed to pass such symbols to llvm intrinsics
git-svn-id: branches/debug_eh@40414 -
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 -
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 -
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 -
it was AT_NONE, which is invalid and should never be used
* explicitly pass the correct value for all calls to those methods elsewhere
in the compiler
git-svn-id: trunk@34250 -
tasmdata.DefineAsmSymbol() and all routines that call it
o will be used to automatically generate AB_INDIRECT sybols when
necessary

list, so that the assembler directives generated for Darwin are emitted
correctly for LLVM
o extracted the library init code generation from hlcgobj to pmodules so
we don't add things to another list than what's passed to
gen_proc_symbol_end(), and so it's done where we generate the init
routine for libraries (rather then checking for every routine whether
it's the init routine for a library)
o removed the llvm-specific gen_proc_symbol_end() because the regular one
now does the same
git-svn-id: trunk@34134 -
moved the code to create the procedure start/end etc. that was at the
call sites of g_external_wrapper() into the new g_external_wrapper()
-> got rid of the x86-specific code in expunix, and fixed expunix for
llvm (e.g. tests/test/tlib1{a,b})
git-svn-id: trunk@34131 -
of the same size -> ensure that this is the case for the shifts in
a_bit_test/set_reg_reg_reg() (fixes tests/tbs/tb0219.pp for llvm)
git-svn-id: trunk@34123 -
(e.g. an empty record): return an "undefined" instance of the result
type (since it's empty, its contents are irrelevant). Before, we
returned "void", but that means returning nothing rather than returning
something empty (part of fixing test/tnoext4 for llvm)
git-svn-id: trunk@34119 -
always be different from the old location, since we just allocated
the registers for the new one above. Should the old registers ever
be needed again for tai_varloc: rr.old/rr.oldhi contains it
