Bug ID: 106623
Summary: internal compiler error: Segmentation fault at
gimple-expr.cc:88
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: ibuclaw at gdcproject dot org
Target Milestone: ---
When compiling with -O1 and above.
---
private struct _Complex(T) { T re; T im; }
enum __c_complex_double : _Complex!double;
pragma(inline, true)
size_t hashOf()(scope const double val)
{
return *cast(size_t*)&val;
}
pragma(inline, true)
size_t hashOf()(scope const _Complex!double val, size_t seed = 0)
{
return hashOf(val.re) + hashOf(val.im);
}
pragma(inline, true)
size_t hashOf()(__c_complex_double val, size_t seed = 0)
{
return hashOf(cast(_Complex!double) val, seed);
}
int main()
{
__c_complex_double val;
return cast(int)hashOf(val);
}
---
The conflating between native complex and struct representation in the code
generation bites us in the optimization pass.

d: Fix internal compiler error: Segmentation fault at gimple-expr.cc:88
Because complex types are deprecated in the language, the new way to
expose native complex types is by defining an enum with a basetype of a
library-defined struct that is implicitly treated as-if it is native.
As casts are not implicitly added by the front-end when downcasting from
enum to its underlying type, we must insert an explicit cast during the
code generation pass.
PR d/106623
gcc/d/ChangeLog:
* d-codegen.cc (underlying_complex_expr): New function.
(d_build_call): Handle passing native complex objects as the
library-defined equivalent.
* d-tree.h (underlying_complex_expr): Declare.
* expr.cc (ExprVisitor::visit (DotVarExp *)): Call
underlying_complex_expr instead of build_vconvert.
gcc/testsuite/ChangeLog:
* gdc.dg/torture/pr106623.d: New test.
