Summary: --inline option fails for complex expressions
Product: D
Version: unspecified
Platform: x86_64
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: russel winder.org.uk

Ignoring all issues of whether the code is good code or even idiomatic code, I
am getting compilation problem with using --inline on complex expressions.
So, for example,
http://www.russel.org.uk/Bazaar/Pi_Quadrature/pi_d2_parallelMapSequentialReduce.d
works fine without --inline but with it fails with:
pi_d2_parallelMapSequentialReduce.d(32): Error: function
std.parallelism.TaskPool.amap!(partialSum).amap!(Result).amap cannot get frame
pointer to execute
However, perhaps more problematic is that
http://www.russel.org.uk/Bazaar/Pi_Quadrature/pi_d2_sequentialMap.d
http://www.russel.org.uk/Bazaar/Pi_Quadrature/pi_d2_sequentialMapParallelReduce.d
work fine without the --inline option but fail with it giving the error:
Internal error: toir.c 178
It is not clear whether this latter is at all related to the former.

I suggest you to minimize that program to the minimal program that shows the
same error, and show it here.

Given the code:
import std.algorithm ;
import std.range ;
import std.stdio ;
import std.typecons ;
double partialSum ( immutable Tuple ! ( int , int , double ) data ) {
return 1.0 ;
}
void execute ( immutable int numberOfTasks ) {
immutable n = 1000000000 ;
immutable delta = 1.0 / n ;
immutable sliceSize = n / numberOfTasks ;
immutable pi = reduce ! ( ( a , b ) => a + b ) ( 0.0 , map ! ( partialSum ) (
map ! ( i => tuple ( i , cast ( int ) sliceSize , cast ( double ) delta ) )
( iota ( numberOfTasks ) ) ) ) ;
}
int main ( immutable string[] args ) {
execute ( 1 ) ;
return 0 ;
}
The problem lies with the cast of sliceSice. Change the parameter to a literal
and it goes away. Change the definition of sliceSize and it goes away.

}
Maybe you are able to trim away some more stuff from that code, to minimize it
some more.

I am hitting the same "Internal error: toir.c 178" even without -inline with
this reduced code:
import std.algorithm: sort;
struct Foo(int m) {
int x;
}
void bar(int m)(Foo!m[] foos) {
void spam() {
//sort!((Foo!m a, Foo!m b) => true)(foos); // no error
sort!((a, b) => true)(foos);
}
}
void main() {
alias Foo!2 F2;
bar([F2(1)]);
alias Foo!3 F3;
bar([F3(2)]);
}

This issue is derived from Issue 7955. Everything you need to create this issue
from Issue 7955 is to wrap lambda template in a nested function.
---
void f(alias fun)() { }
void g(T)() {
void spam() {
f!(a => a)();
}
}
void main() {
g!int();
g!long();
