Moving LET/CONST parsing out of ParseStatement creates some dead branches in
ParseVariableDeclarations(). I'm guessing we can just delete that code,
possibly
replacing it with a few DCHECKs.
https://codereview.chromium.org/869293002/diff/80001/src/parser.cc
File src/parser.cc (right):
https://codereview.chromium.org/869293002/diff/80001/src/parser.cc#newcode2152
src/parser.cc:2152: if (var_context == kStatement) {
I believe this code is now unreachable...
https://codereview.chromium.org/869293002/diff/80001/src/parser.cc#newcode2172
src/parser.cc:2172: if (var_context == kStatement) {
...as is this.
https://codereview.chromium.org/869293002/diff/80001/src/parser.cc#newcode2451
src/parser.cc:2451: return nullptr;
Nit: the rest of the code in this file still uses "NULL"
https://codereview.chromium.org/869293002/diff/80001/src/preparser.cc
File src/preparser.cc (right):
https://codereview.chromium.org/869293002/diff/80001/src/preparser.cc#newcode450
src/preparser.cc:450: if (var_context != kSourceElement && var_context
!= kForStatement) {
Same dead code as in parser...
https://codereview.chromium.org/869293002/diff/80001/src/preparser.cc#newcode466
src/preparser.cc:466: if (var_context != kSourceElement && var_context
!= kForStatement) {
...and here too.
