--- Comment #2 from Martin Nowak c...@dawg.eu ---
Mmh, the codegen assertion vanished with this commit
(https://github.com/D-Programming-Language/dmd/commit/9efe7f74c2462e8743f5a479cd04f9be733be4b0).
I reproduced another test case for the issue.
cat bug.d CODE
struct FPoint
{
float x, y;
}
struct FRect
{
float left, top, right, bottom;
static FRect calcBounds(FPoint[] )
{
return FRect();
}
}
struct Matrix
{
FRect mapRect(FRect src) {
FPoint[] pts = new FPoint[](1);
pts[0].x = src.left;
pts[0].y = src.top;
return FRect.calcBounds(pts);
}
}
// TODO: FPoint - Point!T
struct Path
{
@property FRect bounds()
{
if (points.length)
return FRect();
else
return FRect();
}
FPoint[] points;
}
void foo()
{
Matrix mat;
Path path;
mat.mapRect(path.bounds);
}
CODE
The issues first appeared with dmd2.060 and seems to be triggered by assigning
tym = TYucent to 16 byte structs that consist of either 4 floats or 2 doubles
in elstruct
(https://github.com/D-Programming-Language/dmd/blob/5cc1c812227440d199f265dec8fb976bea7ad943/src/backend/cgelem.c#L3077).
I don't understand that code good enough to fix the issue though.
