[Issue 20788] New: Difference between colored and non colored output

[d-bugmail--- via Digitalmars-d-bugs]

https://issues.dlang.org/show_bug.cgi?id=20788

  Issue ID: 20788
   Summary: Difference between colored and non colored output
   Product: D
   Version: D2
  Hardware: All
OS: All
Status: NEW
  Severity: enhancement
  Priority: P1
 Component: dmd
  Assignee: nob...@puremagic.com
  Reporter: an...@s-e-a-p.de

The dmd output text is different depending whether color output is on or off.

Sample:

void main()
{
int i;
e = 3;
}

Color on:
sample.d(4): Error: undefined identifier e

Color off:
sample.d(4): Error: undefined identifier `e`

This is an issue if you want to use the dmd output for dustmite.
Color is on by default and very often I forgot, that I cannot just
use the output of dub (dmd) but have to disable colored output.

The dmd output text should be the same, independent whether color is
on or off.

Once the patch for bug 19550 is applied, this bug should be a duplicate of bug
#7157.

The common issue with #7157 is that `aewalk` use an O(N) search for available
expressions to reduce expressions. This subsequently leads to a blow of
`el_match` calls.

It should be possible to fix this by changing the O(N) search to a sorted
search or hashing scheme.

Ok I believe to have found the culprit:
There is a special case for OPcomma here, which traverses the entire list of
elems:
https://github.com/dlang/dmd/blob/793635ea7ad3cf30c02bf1b5d51eefdc166c8b82/src/dmd/backend/gflow.d#L624

But `accumaecpx`already recurses over the list of elems:
https://github.com/dlang/dmd/blob/793635ea7ad3cf30c02bf1b5d51eefdc166c8b82/src/dmd/backend/gflow.d#L1102
at `accumaecpx(n.EV.E2);`
