Janneke Nieuwenhuizen 6f5aeed75a DRAFT mescc: Hide assign size ERROR as WARNING behind MESCC_DEBUG. 
* module/mescc/compile.scm (expr->register): Only output inexplicable
size warning when MESCC_DEBUG environment variable is set.

Ekaitz Zarraga 47cffc5d2a mescc: Fix switch statements' fallthrough 
Flattens case structures as nyacc is giving consecutive cases as a
nested block like:

    (case testA
      (case testB
        (case testC BODY)))

We convert to:

    ((case testA (expr-stmt))
     (case testB (expr-stmt))
     (case testC BODY))

And then treat them as independent cases. For the fallthrough we just
add a jump to each case's body right before its clause (each of the case
blocks is responsible of adding its own jump to its body):

        // This doesn't have it because it's the first
    CASE1:
        testA
    CASE1_BODY:

        goto CASE2_BODY
    CASE2:
        testB
    CASE2_BODY:

        goto CASE3_BODY
    CASE3:
        testB
    CASE3_BODY:

This enables complex fallthrough schemes comparing to what was done
before.

variable.
(ast->info)[switch]{statements}: Use flatten-cases on it.

    mescc: Refactor variable declaration.

There was a debug "22" leaking in compile.scm.  It should be a "0".

W. J. van der Laan edf397038a mescc: Add r0-cmp-r1 instruction. 
This instruction is used to compare two registers and set the flags
accordingly. In current architectures this is the same as r0-r1, but for
RISCV it will be different.  RISC-V does not have condition flags so
(until a better solution) we are going to emulate them there.

* module/mescc/armv4/as.scm (armv4:instructions): Add r0-cmp-r1 as alias
of r0-r1.
* module/mescc/i386/as.scm: Same.
* module/mescc/x86_64/as.scm: Same.
* module/mescc/compile.scm (expr->register): Make use of the new
r0-cmp-r1 instruction.

mescc: Only use signed division when numerator is signed. 
Currently, sign-extension (CLTD vs XOR EDX) and signed division (IDIV vs
DIV) selected by setting "signed?".  See, module/mescc/x86/as.scm.
Possibly we need a signed? based on numerator and denominator, and
add a extend-sign? based on the signedness of the numerator?

* module/mescc/compile.scm (expr->register): Base "signed?" strictly on
signedness of numerator.
