as older assembler do not support 64-bit instructions use in there.
* Use .byte substitutes for ldmxcsr and movaps instructions
git-svn-id: trunk@37008 -
* 'mxcsr' variable made public and renamed to DefaultMXCSR.
* GetSSECSR and SetSSECSR renamed to GetMXCSR and SetMXCSR, respectively. Previous names continue to exist as deprecated aliases.
git-svn-id: trunk@27656 -
get_caller_frame, get_caller_addr and dump_stack
with default NIL value to systemh.inc.
+ Added new get_addr function.
system.inc: Use get_addr and get_frame to call
HandleErrorAddrFrame instead of HandleErrorFrame
in several error functions.
Modify dump_stack to use frame and addr parameters.
Provide a dummy get_addr function returning nil.
i386/i386.inc, x86_64./x86_64.inc: Provide real
implementation of get_addr function.
git-svn-id: trunk@21697 -
* Modified fpc_ansistr_decr_ref and fpc_widestr_decr_ref so they always zero the pointer passed by reference. Other _decr_ref helpers already do it.
- Removed tcg.g_decrrefcount, calling cg.g_finalize instead.
- finalize_data_node and tcg.g_finalize: removed code generation for zeroing locations, because it is now done by RTL helpers. This further reduces code size.
As a total result of this change and r20118, the size of Lazarus executable is reduced by about 12%.
git-svn-id: trunk@20119 -
- i386-specific fpc_shortstr_append_shortstr removed too, because a) it was anyway disabled with STR_CONCAT_PROCS, b) the generic implementation is smaller and probably faster due to optimized Move().
git-svn-id: trunk@19867 -
* disallow pushfd/popfd for x86_64 (mantis #14862)
* fixed assembling popfq with the internal assembler (it needs a rex.w
prefisx, while pushfq doesn't)
* changed the default opcode size of pushf/popf/pusha/popa in
{$asmmode intel} from "native size" to 16 bit (compatible with Intel
manuals and Kylix; in AT&T mode, the default size for those operations
remains the native one)
* changed pushf/popf in rtl/i386/* into pushfd/popfd because of the
previous change
git-svn-id: trunk@15546 -
o fixed gprof under linux/i386
o fixed pic-compilation of the linux/i386 rtl
o initialisation of linux shared libraries is now possible with pic-code
git-svn-id: trunk@13703 -
o i386/i386.inc used a function (fpc_truely_ansistr_unique) is now
only included if FPC_HAS_FEATURE_ANSISTRINGS is enabled (all other
platforms use the Pascal-only implementations)
o inc/heap.inc relied on threading
o inc/threads.inc relied on exceptions, consoleio and stackcheck
o inc/system.inc: just a feature-related "variable not used"-hint
git-svn-id: trunk@13121 -
multi-platform version of patch in r12461, which caused the i386 version
of fpc_pchar_length to return 0 in all cases, which used tabs, and did
not include a test case)
