Bug #: 50
Summary: Slowdown compiling static data for large arrays.
Classification: Unclassified
Product: GDC
Version: development
Platform: x86
OS/Version: All
Status: NEW
Severity: normal
Priority: Normal
Component: gdc
AssignedTo: ibuc...@gdcproject.org
ReportedBy: ibuc...@gdcproject.org
There has been a massive slowdown in generating static data for large arrays
since removing the dmd dt_t and replacing with trees.
Main problem is that we spend most of the time in dt_last which iterates:
0 .. 1
0 .. 2
0 .. 3
....
0 .. 524277
0 .. 524278
0 .. 524279
That is a total of 137435021340 loops just to generate an array.
Minimal test:
---
int[524280] foo;
--
