As Stefan mentioned, a test case would be nice. But have you 
tried annotating the offending function with pragma(inline, 
false)?

Thanks.

I've tried pragma(inline,false), it didn't help.

Maybe I'l should try more way to locate the problem.

Thanks.

If you are certain that your code is 100% correct, please file 
a bug report. Inlining is done by LLVM and it is rare to find 
an LLVM bug like that (what architecture are you on, x86?).


While LLVM in general has quite a few bugs, inlining should be 
rather solid.

 Any chance we can get a test-case ?


Thanks.

I've tried to get a test-case, but they couldn't core dump.

You can try disabling inlining of a specific function 
(pragma(inline, false)), or disabling optimization inside a 
function (@optStrategy("none")).

I'm not so sure about the 100% correct. It's just the 
"disable-inlining" flag that make thought it's a inline problem.

I've just tried these.
(pragma(inline, false)) didn't work and (@optStrategy("none")) 
produced a error of "Error: undefined identifier 'optStrategy'.

You could file a bug/feature request with Dub: I think it 
should add user flags at the end of the cmdline. (flags can 
override earlier flags, so then the user can override any flag 
Dub is already passing to LDC).

how to disable inlining of ldc2 when 'dub build --build=release'?

2017-05-20 Thread lixiaozi via Digitalmars-d-learn 

Hi,guys!
I recently use ldc2 to compile my project.
When using 'dub build --build=release --compiler=ldc2 ',it 
crashed in a try catch block.
After a few tries, I noticed it's the inline optimization in ldc2 
that caused the crash. So i manually changed the call of ldc2 to 
'ldc2 -release -disable-inlining -Hkeep-all-bodies -O3 -w -oq 
...' and it worked and doesn't crash any more.


Now, I try to disable inlining in "dub.json" like
==
"dflags":[
"-disable-inlining"
],
==
 but it doesn't work, because then dub calls ldc2 like this:
'ldc2   -disable-inlining  -release  -enable-inlining 
-Hkeep-all-bodies -O3 -w -oq' and inlining in ldc2 will still be 
enabled.


so, what should i do to disable inlining of ldc2 in release build?

Thanks in advance.
