# Experimental syntax sugar for SubX programs.

# To run:
|
|
# $ ./subx translate 0*.subx apps/subx-common.subx apps/desugar.subx -o apps/desugar
|
|
#
|
|
# We're experimenting with the following expressions:
|
|
#
|
|
# 1.
|
|
# $ echo "ab %eax" | ./subx run apps/desugar
|
|
# ab 3/mod 0/rm32
|
|
#
|
|
# 2.
|
|
# $ echo "ab *eax" | ./subx run apps/desugar
|
|
# ab 0/mod 0/rm32
|
|
#
|
|
# 3.
|
|
# $ echo "ab *(eax+4)" | ./subx run apps/desugar
|
|
# ab 2/mod 0/rm32 4/disp32
|
|
#
|
|
# 4.
|
|
# $ echo "ab *(eax+ecx)" | ./subx run apps/desugar
|
|
# ab 0/mod 4/rm32 0/base 1/index 0/scale
|
|
#
|
|
# 5.
|
|
# $ echo "ab *(eax+ecx+4)" | ./subx run apps/desugar
|
|
# ab 2/mod 4/rm32 0/base 1/index 0/scale 4/disp32
|
|
#
|
|
# 6.
|
|
# $ echo "ab *(eax+ecx<<2+4)" | ./subx run apps/desugar
|
|
# ab 2/mod 4/rm32 0/base 1/index 2/scale 4/disp32
|
|
#
|
|
# Addition isn't commutative here. Template must always be (base+index<<scale+disp),
|
|
# though some components are optional as described above.
