| version 1.68 (Jun 13, 2009) |
| |
| [+] Added SSSE3 (Supplemental SSE3), SSE4.1, SSE4.2 and SSE4a instructions. |
| |
| [+] Added the AMD SVM and Intel SMX instructions. |
| |
| [+] Added "rdmsrq", "wrmsrq", "sysexitq" and "sysretq" mnemonics for the |
| 64-bit variants of respective instructions. |
| |
| [+] Added "fstenvw", "fstenvd", "fsavew", "fsaved", "frstorw" and "frstord" |
| mnemonics to allow choosing between 16-bit and 32-bit variants of |
| structures used by the "fstenv", "fsave" and "frstor" instructions. |
| |
| [+] Added "plt" operator for the ELF output format. |
| |
| [+] Allowed "rva" operator to be used in MS COFF object format, and also |
| added "static" keyword for the "public" directive. |
| |
| [+] Added Intel-style aliases for the additional long mode 8-bit registers. |
| |
| [-] The PE formatter now automatically detects whether relocatable labels |
| should be used, depending on whether the fixups directory is placed |
| somewhere into executable by programer, or not. This makes possible the |
| more flexible use of the addressing symbols in case of PE executable fixed |
| at some position. |
| |
| [-] Added support for outputting the 32-bit address relocations in case of |
| 64-bit object formats and PE executable. This makes some specific |
| instructions compilable, but it also forces linker to put such |
| generated code into the low 2 gigabytes of addressing space. |
| |
| [+] Added "EFI", "EFIboot" and "EFIruntime" subsystem keywords for PE format. |
| |
| [-] Corrected the precedence of operators of macroinstruction line maker. |
| The symbol escaping now has always the higher priority than symbol conversion, |
| and both have higher precedence than concatenation. |
| |
| [+] Allowed to check "@b" and "@f" symbols with "defined" operator. |
| |
| [+] Allowed "as" operator to specify the output file extension when |
| placed at the end of the "format" directive line. |
| |
| [-] Definition of macro with the same name as one of the preprocessor's directives |
| is no longer allowed. |
| |
| [+] Allowed single quote character to be put inside the number value, |
| to help improve long numbers readability. |
| |
| [+] Added optional symbolic information output, and a set of tools that extract |
| various kinds of information from it. |
| |
| [+] Added "err" directive that allows to signalize error from the source. |
| |
| |
| version 1.66 (May 7, 2006) |
| |
| [+] Added "define" directive to preprocessor, which defines symbolic constants, |
| the same kind as "equ" directive, however there's an important difference |
| that "define" doesn't process symbolic constants in the value before |
| assigning it. For example: |
| |
| a equ 1 |
| a equ a+a |
| |
| define b 1 |
| define b b+b |
| |
| defines the "a" constant with value "1+1", but the "b" is defined with |
| value "b+b". This directive may be useful in some advanced |
| macroinstructions. |
| |
| [-] Moved part of the conditional expression processing into parser, |
| for slightly better performance and lesser memory usage by assembler. |
| The logical values defined with "eq", "eqtype" and "in" operators are now |
| evaluated by the parser and if they are enough to determine the condition, |
| the whole block is processed accordingly. Thus this block: |
| |
| if eax eq EAX | 0/0 |
| nop |
| end if |
| |
| is parsed into just "nop" instruction, since parser is able to determine |
| that the condition is true, even though one of the logical values makes no |
| sense - but since this is none of the "eq", "eqtype" and "in" expressions, |
| the parser doesn't investigate. |
| |
| [-] Also the assembler is now calculating only as many logical values as it |
| needs to determine the condition. So this block: |
| |
| if defined alpha & alpha |
| |
| end if |
| |
| will not cause error when "alpha" is not defined, as it would with previous |
| versions. This is because after checking that "defined alpha" is false |
| condition it doesn't need to know the second logical value to determine the |
| value of conjunction. |
| |
| [+] Added "short" keyword for specifying jump type, the "jmp byte" form is now |
| obsolete and no longer correct - use "jmp short" instead. |
| |
| [-] The size operator applied to jump no longer applies to the size of relative |
| displacement - now it applies to the size of target address. |
| |
| [-] The "ret" instruction with 0 parameter is now assembled into short form, |
| unless you force using the 16-bit immediate with "word" operator. |
| |
| [+] Added missing extended registers for the 32-bit addressing in long mode. |
| |
| [+] Added "linkremove" and "linkinfo" section flags for MS COFF output. |
| |
| [+] Added support for GOT offsets in ELF object formatter, which can be useful |
| when making position-independent code for shared libraries. For any label |
| you can get its offset relative to GOT by preceding it with "rva" operator |
| (the same keyword as for PE format is used, to avoid adding a new one, |
| while this one has very similar meaning). |
| |
| [-] Changed ELF executable to use "segment" directive in place of "section", |
| to make the distinction between the run-time segments and linkable |
| sections. If you had a "section" directive in your ELF executables and they |
| no longer assemble, replace it with "segment". |
| |
| [-] The PE formatter now always creates the fixups directory when told to - |
| even when there are no fixups to be put there (in such case it creates the |
| directory with one empty block). |
| |
| [-] Some of the internal structures have been extended to provide the |
| possibility of making extensive symbol dumps. |
| |
| [-] Corrected "fix" directive to keep the value intact before assigning it to the |
| prioritized constant. |
| |
| [+] The ` operator now works with any kind of symbol; when used with quoted |
| string it simply does nothing. Thus the sequence of ` operators applied to |
| one symbol work the same as if there was just one. In similar manner, the |
| sequence of # operators now works as if it was a single one - using such a |
| sequence instead of escaping, which was kept for some backward |
| compatibility, is now deprecated. |
| |
| [-] Corrected order of identifying assembler directives ("if db eq db" was |
| incorrectly interpreted as data definition). |
| |
| [-] Many other small bugs fixed. |
| |
| |
| version 1.64 (Aug 8, 2005) |
| |
| [+] Output of PE executables for Win64 architecture (with "format PE64" |
| setting). |
| |
| [+] Added "while" and "break" directives. |
| |
| [+] Added "irp" and "irps" directives. |
| |
| [+] The macro arguments can be marked as required with the "*" character. |
| |
| [-] Fixed checking for overflow when multiplying 64-bit values - the result |
| must always fit in the range of signed 64 integer now. |
| |
| [-] Segment prefixes were generated incorrectly in 16-bit mode when BP was used |
| as a second addressing register - fixed. |
| |
| [-] The "local" directive was not creating unique labels in some cases - fixed. |
| |
| [-] The "not encodable with long immediate" error in 64-bit mode was sometimes |
| wrongly signaled - fixed. |
| |
| [-] Other minor fixes and corrections. |
| |
| |
| version 1.62 (Jun 14, 2005) |
| |
| [+] Escaping of symbols inside macroinstructions with backslash. |
| |
| [+] Ability of outputting the COFF object files for Win64 architecture |
| (with "format MS64 COFF" setting). |
| |
| [+] New preprocessor directives: "restruc", "rept" and "match" |
| |
| [+] VMX instructions support (not documented). |
| |
| [+] Extended data directives to allow use of the "dup" operator. |
| |
| [+] Extended "struc" features to allow custom definitions of main structure's |
| label. |
| |
| [-] When building resources from the the .RES file that contained more |
| than one resource of the same string name, the separate resource |
| directories were created with the same names - fixed. |
| |
| [-] Several bugs in the ELF64 object output has been fixed. |
| |
| [-] Corrected behavior of "fix" directive to more straightforward. |
| |
| [-] Fixed bug in "include" directive, which caused files included from within |
| macros to be processed the wrong way. |
