* fixed g_external_wrapper for darwin/i386 (both with and without pic,
by using a_jmp_name(), because the darwin jump stubs can always
be called directly)
git-svn-id: trunk@8669 -
to be made pic-safe (mainly accesses to the global default8087cw)
* At the same time also made the non-pic code abi-compliant (access
external data via indirect symbol pointers etc)
Darwin/i386 also puts the got into a virtual register (like
Darwin/ppc), a.o. because the register allocator fails to colour
a routine in aasmcpu.pas if we take away ebx from it.
git-svn-id: trunk@8657 -
* small cleanups of unused variables in firstpass
* node_resources_fpu() created to get an approximation of the
required fpu registers
* for the moment use node_complexity in the CG until the
node_resource_int() is created
git-svn-id: trunk@8655 -
without relocations in sec_rodata_norel. It should be possible to make
this new section read-only on all platforms, although currently it
is only done for darwin, and for non-pic code written using the
-Aas assembler writer.
Most platforms also have a special section for "constant but with
relocations" data, but such a section is currently only used for
Darwin (others still use plain .data sections for that, like they
did before)
git-svn-id: trunk@8650 -
* refactored above mentioned stub code generation, allowing the CG to define a cpu specific method for this task by overriding new g_external_wrapper() method
git-svn-id: trunk@8566 -
* fixed set add-nodes in case left and right are swapped (taddset4)
* fixed "in" expressions with packed sets in case left is < setbase
(now tested by tw8258b, which was missing a {$packset 1} directive)
git-svn-id: trunk@8519 -
is <> 0 (Delphi compatible now, + various tests)
+ support for enums and sets in is_in_limit()
* fixed converting smallset expressions to varsets
* improved choosing an appropriate common set type when mixing
set types in an expression
- removed no longer used normalset code from nadd.pas
- disabled large set (>256 elements) support for now, because
they are not yet supported entirely throughout the compiler
and this causes errors at run time in several situations
git-svn-id: trunk@8515 -
- {$intpromotion common_type} or -CIcommon_type switches to common type promotion.
- {$intpromotion native_integer} or -CIcommon_type switches to current behaviour.
- Default in tp mode is common_type, native_integer in other modes
- Compiler can cycle with -CIcommon_type
- Still needs checking on other architectures than i386
git-svn-id: trunk@8118 -
* fixed generic and x86 in-code in case genjumps=true and
complexity(right)>complexity(left) (not sure if possible
in practice currently, but better safe than sorry)
git-svn-id: trunk@7912 -
* added LOC_CONSTANT to the list of allowed locations for the left
hand side of an in-node, so it doesn't get forced into a register
anymore in that case
git-svn-id: trunk@7831 -
* varsets ({$packset x}) are now supported on big endian targets
* gdb now displays sets properly on big endian systems
* cleanup of generic set code (in, include/exclude, helpers), all
based on "bitpacked array[] of 0..1" now
* there are no helpers available yet to convert sets from the old to
the new format, because the set format will change again slightly
in the near future (so that e.g. a set of 24..31 will be stored in
1 byte), and creating two classes of set conversion helpers would
confuse things (i.e., it's not recommended to use trunk currently for
programs which load sets stored to disk by big endian programs compiled
by previous FPC versions)
* cross-endian compiling has been tested and still works, but one case
is not supported: compiling a compiler for a different endianess
using a starting compiler from before the current revision (so first
cycle natively, and then use the newly created compiler to create a
cross-compiler)
