It needs an extra pass to compute the size of the constant table for the
l32r instructions.
py/emitinline: Move common code for end of final pass to compiler.2016-12-09T10:23:17+00:00Damien Georgedamien.p.george@gmail.com2016-12-09T10:23:17+00:00urn:sha1:e920bab9768f71c7e22fcfc5af3e1c40f2db8eeb
This patch moves some common code from the individual inline assemblers to
the compiler, the code that calls the emit-glue to assign the machine code
to the functions scope.
py/emitinline: Move inline-asm align and data methods to compiler.2016-12-09T09:54:54+00:00Damien Georgedamien.p.george@gmail.com2016-12-09T09:54:54+00:00urn:sha1:dd53b12193dca4800ab207170fcc883142dd0f22
These are generic methods that don't depend on the architecture and so
can be handled directly by the compiler.
py: Add inline Xtensa assembler.2016-12-09T06:07:38+00:00Damien Georgedamien.p.george@gmail.com2016-12-09T06:03:33+00:00urn:sha1:f76b1bfa9f59fcfa03837c6934ad51d2db3ff4a3
This patch adds the MICROPY_EMIT_INLINE_XTENSA option, which, when
enabled, allows the @micropython.asm_xtensa decorator to be used.
The following opcodes are currently supported (ax is a register, a0-a15):
ret_n()
callx0(ax)
j(label)
jx(ax)
beqz(ax, label)
bnez(ax, label)
mov(ax, ay)
movi(ax, imm) # imm can be full 32-bit, uses l32r if needed
and_(ax, ay, az)
or_(ax, ay, az)
xor(ax, ay, az)
add(ax, ay, az)
sub(ax, ay, az)
mull(ax, ay, az)
l8ui(ax, ay, imm)
l16ui(ax, ay, imm)
l32i(ax, ay, imm)
s8i(ax, ay, imm)
s16i(ax, ay, imm)
s32i(ax, ay, imm)
l16si(ax, ay, imm)
addi(ax, ay, imm)
ball(ax, ay, label)
bany(ax, ay, label)
bbc(ax, ay, label)
bbs(ax, ay, label)
beq(ax, ay, label)
bge(ax, ay, label)
bgeu(ax, ay, label)
blt(ax, ay, label)
bnall(ax, ay, label)
bne(ax, ay, label)
bnone(ax, ay, label)
Upon entry to the assembly function the registers a0, a12, a13, a14 are
pushed to the stack and the stack pointer (a1) decreased by 16. Upon
exit, these registers and the stack pointer are restored, and ret.n is
executed to return to the caller (caller address is in a0).
Note that the ABI for the Xtensa emitters is non-windowing.
py: Allow inline-assembler emitter to be generic.2016-12-09T06:06:21+00:00Damien Georgedamien.p.george@gmail.com2016-12-09T02:17:49+00:00urn:sha1:ad297a1950c74c35c90dd655ae9a69d33ed28dc0
This patch refactors some code so that it is easier to integrate new
inline assemblers for different architectures other than ARM Thumb.
py: Integrate Xtensa assembler into native emitter.2016-12-09T05:51:49+00:00Damien Georgedamien.p.george@gmail.com2016-12-09T05:39:39+00:00urn:sha1:8e5aced1fd4845b23b203d8d15f9b34b6b022ceb
The config option MICROPY_EMIT_XTENSA can now be enabled to target the
Xtensa architecture with @micropython.native and @micropython.viper
decorators.

Short circuiting is handled correctly by c_if_cond, and constants within
short-circuit expressions are optimised by the parser.
py/parse: Make mp_parse_node_new_leaf an inline function.2016-11-15T05:48:48+00:00Damien Georgedamien.p.george@gmail.com2016-11-13T04:35:11+00:00urn:sha1:ed9c93f0f13fe2b6b4b0fbc1155b1e38ee1be242
It is split into 2 functions, one to make small ints and the other to make
a non-small-int leaf node. This reduces code size by 32 bytes on
bare-arm, 64 bytes on unix (x64-64) and 144 bytes on stmhal.
