why:
the v2 prefix of the file name was used as a visual aid when
comparing vm2 against vm sources
details:
all renamed v2*.nim sources compile locally with the -d:kludge:1 flag
set or without (some work with either)
only sources not renamed yet: v2state_transactions.nim
why:
subsequent development will compile sources as main without setting
the vm2_enabled flag. also, the doc generator would fail an vm2 without
setting the flag for the vm2 files.
why:
activate NIM comments needed re-write. as there is no advantage in using
the macro replacing a few missing op-codes by "Nop##" name symbols, the
macro wrapper has been removed.
details:
when explicitly accessed by numeric value ##, missing Op enum entries
result in a symbol name something like "Op ##".
rather than implicitly using a macro to fix the op-codes list, missing
entries are detected at compile time when a fatal exception is thrown.
the static compile time check verifies that
all op-codes 0 .. 255 are defined
op code name/mnemonic has at least 2 chars and starts with a capital
op code name/mnemonic is not NIM auto-generated (i.e. has a space)
also, original '#' comments are exposed as doc comments '##'
why:
these files provide part of the externally accessible interface
provided by vm_cpmputation.nim, vm_internals.nim. so the
new filename indicates that the source code belongs to vm2 (rather
than vm).
why:
these files provide part of the externally accessible interface
provided by vm_types*.nim. so the new filename indicates that the
source code belongs to vm2 (rather than vm).
why:
making sure that deep links into vm2 sources are configured properly. it
is intended that only the vm_*.nim interface headers are allowed to
source files in vm2. the sentinels just protect from coding errors.
why:
vm2 enabled by ENABLE_VM2=1 behaves as vm without ENABLE_EVMC=1 until
it doesn't in some future fatch set. this leaves some wiggle room
to work on a vm copy without degrading the original implementation.
details:
+ additional make flag ENABLE_VM2=1 (or ENABLE_VM2=0 to explicitely disable)
+ when both flags ENABLE_EVMC=1 and ENABLE_VM2=1 are present, the former
flag ENABLE_EVMC=1 takes precedence, this is implemented at the NIM
compiler level for -d:evmc_enabled and -d:vm2_enabled
