Make fixes, improvements, and chibicc python bindings
- python now mixes audio 10x faster - python octal notation is restored - chibicc now builds code 3x faster - chibicc now has help documentation - chibicc can now generate basic python bindings - linenoise now supports some paredit-like features See #141

ASSEMBLER
|
||||
|
||||
That process is normally an implementation detail of your compiler,
|
||||
which can embed this program or launch it as a subprocess. Much GNU
|
||||
style syntax is supported. Your code that gets embedded in an asm()
|
||||
statement will ultimately end up here. This implementation, has the
|
||||
advantage of behaving the same across platforms, in a simple single
|
||||
file implementation that compiles down to a 100kilo ape executable.
|
||||
|
||||
Your assembler supports the following flags:
|
||||
|
||||
-o FILE output path [default: a.out]
|
||||
-I DIR append include path [default: .]
|
||||
-W inhibit .warning
|
||||
-Z inhibit .error and .err
|
||||
|
||||
Your assembler supports the following directives:
|
||||
|
||||
.zero N emits 0's
|
||||
.byte INT... emits int8
|
||||
.word INT... emits int16
|
||||
.long INT... emits int32
|
||||
.quad INT... emits int64
|
||||
.octa INT... emits int128
|
||||
.ascii STR... emits string
|
||||
.asciz STR... emits string and 0 byte
|
||||
.ident STR emits string to .comment section
|
||||
.float NUMBER... emits binary32
|
||||
.double NUMBER... emits binary64
|
||||
.float80 NUMBER... emits x86 float (10 bytes)
|
||||
.ldbl NUMBER... emits x86 float (16 bytes)
|
||||
.zleb128 NUMBER... emits LEB-128 zigzag varint
|
||||
.sleb128 NUMBER... emits LEB-128 signed varint
|
||||
.uleb128 NUMBER... emits LEB-128 unsigned varint
|
||||
.align BYTES [FILL [MAXSKIP]] emits fill bytes to boundary
|
||||
.end halts tokenization
|
||||
.abort crashes assembler
|
||||
.err aborts (ignorable w/ -Z)
|
||||
.error STR aborts (ignorable w/ -Z)
|
||||
.warning STR whines (ignorable w/ -W)
|
||||
.text enters text section (default)
|
||||
.data enters data section
|
||||
.bss enters bss section
|
||||
.section NAME [SFLG SHT] enters section
|
||||
.previous enters previous section
|
||||
.pushsection NAME [SFLG SHT] pushes section
|
||||
.popsection pops section
|
||||
.type SYM TYPE sets type of symbol
|
||||
.size SYM EXPR sets size of symbol
|
||||
.internal SYM... marks symbol STV_INTERNAL
|
||||
.hidden SYM... marks symbol STV_HIDDEN
|
||||
.protected SYM... marks symbol STV_PROTECTED
|
||||
.globl SYM... marks symbol STB_GLOBAL
|
||||
.local SYM... marks symbol STB_LOCAL
|
||||
.weak SYM... marks symbol STB_WEAK
|
||||
.include FILE assembles file source
|
||||
.incbin FILE emits file content
|
||||
.file FILENO PATH dwarf file define
|
||||
.loc FILENO LINENO dwarf source line
|
||||
|
||||
TYPE can be one of the following:
|
||||
|
||||
- @notype STT_NOTYPE (default)
|
||||
- @object STT_OBJECT
|
||||
- @function STT_FUNC
|
||||
- @common STT_COMMON
|
||||
- @tls_object STT_TLS
|
||||
|
||||
SHT can be one of the following:
|
||||
|
||||
- @progbits SHT_PROGBITS
|
||||
- @note SHT_NOTE
|
||||
- @nobits SHT_NOBITS
|
||||
- @preinit_array SHT_PREINIT_ARRAY
|
||||
- @init_array SHT_INIT_ARRAY
|
||||
- @fini_array SHT_FINI_ARRAY
|
||||
|
||||
SFLG is a string which may have the following characters:
|
||||
|
||||
- a SHF_ALLOC
|
||||
- w SHF_WRITE
|
||||
- x SHF_EXECINSTR
|
||||
- g SHF_GROUP
|
||||
- M SHF_MERGE
|
||||
- S SHF_STRINGS
|
||||
- T SHF_TLS

RICHARD STALLMAN MATH55 ASM() NOTATION
|

|
||||
BEHAVIOR
|
||||
|
||||
=: write-only
|
||||
+: read/writeable
|
||||
|
||||
SELECTION
|
||||
|
||||
Autonomous
|
||||
|
||||
a: ax/eax/rax
|
||||
b: bx/ebx/rbx
|
||||
c: bx/ebx/rbx
|
||||
d: dx/edx/rdx
|
||||
S: si/esi/rsi
|
||||
D: di/edi/rdi
|
||||
|
||||
Algorithmic
|
||||
|
||||
r: pick one of a,b,c,d,D,S,bp,sp,r8-15 registers, referenced as %0,etc.
|
||||
l: pick one of a,b,c,d,D,S,bp,r8-15 for indexing, referenced as %0,etc.
|
||||
q: pick one of a,b,c,d,r8-r15 for lo-byte access, e.g. %b0,%w0,%k0,etc.
|
||||
Q: pick one of a,b,c,d for hi-byte access, e.g. %h0,etc.
|
||||
U: pick one of a,c,d,D,S,r8-11 (call-clobbered)
|
||||
R: pick one of a,b,c,d,D,S,bp,sp (all models)
|
||||
y: pick mmx register
|
||||
x: pick sse register
|
||||
X: pick anything
|
||||
m: memory
|
||||
o: memory offsetable by an immediate, referenced as %0,2+%0,etc.
|
||||
p: memory, intended for load/push address and segments (movl %@:%p1, %0)
|
||||
g: probably shorthand for "rmi" combo
|
||||
X: allow anything
|
||||
|
||||
Combos
|
||||
|
||||
rm: pick register or memory address (converting immediates)
|
||||
rmi: pick register or memory address (allowing immediates)
|
||||
|
||||
Immediates
|
||||
|
||||
i: integer literal or compiler/assembler constexpr or linker embedding
|
||||
e: i∊[-2^31,2^31) for sign-extending immediates
|
||||
Z: i∊[0,2^32) for zero-extending immediates
|
||||
I: i∊[0,31] (5 bits for 32-bit shifts)
|
||||
J: i∊[0,63] (6 bits for 64-bit shifts)
|
||||
K: i∊[-128,127]
|
||||
L: permit uncasted char/short literal as zero-extended operand to andl?
|
||||
M: i∊[0,3] (intended for index scaling, e.g. "mov\t(?,?,1<<%0),?")
|
||||
N: i∊[0,255] (for in & out)
|
||||
M: 2-bit integer constant (shifts for index scaling)
|
||||
I: 5-bit integer constant (for 32-bit shifts)
|
||||
J: 6-bit integer constant (for 64-bit shifts)
|
||||
|
||||
Transcendentals
|
||||
|
||||
f: any stack slot
|
||||
t: top of stack (%st(0)) and possibly converts xmm to ymm
|
||||
u: second top of stack (%st(1))
|
||||
|
||||
Specials
|
||||
|
||||
%= generates number unique to each instance
|
||||
%%REG explicitly-supplied register (used w/ clobbers)
|
||||
|
||||
AUGMENTATION
|
||||
|
||||
%pN print raw
|
||||
%PN print w/ @plt
|
||||
%aN print address
|
||||
%zN print only opcode suffix for operand type
|
||||
%lN print label without punctuation, e.g. jumps
|
||||
%cN print immediate w/o punctuation, e.g. lea %c0(%1),%2
|
||||
%bN print lo-byte form, e.g. xchgb %b0,%%al (QImode 8-bit)
|
||||
%hN print hi-byte form, e.g. xchgb %h0,%%ah (QImode 8-bit)
|
||||
%wN print word form, e.g. xchgw %w0,%%ax (HImode 16-bit)
|
||||
%kN print dword form, e.g. xchgl %k0,%%eax (SImode 32-bit)
|
||||
%qN print qword form, e.g. xchgq %q0,%%rax (DImode 64-bit)
|
||||
%HN access high 8 bytes of SSE register, or +8 displacement
|
||||
%nN negated literal, e.g. lea %n0(%1),%2
|
||||
%VN print register name without %, e.g. call foo%V0
|
||||
|
||||
