Inlining warning

Question

I am getting inlining warnings after compilation in 64 bit Linux machine. The compiler is :

gcc (Ubuntu 4.4.1-4ubuntu9) 4.4.1

The warnings are :

warning: inlining failed in call to ‘list_Cons’: call is unlikely and code size would grow
warning: called from here
warning: inlining failed in call to ‘list_List’: call is unlikely and code size would grow
warning: called from here
warning: inlining failed in call to ‘list_Cons’: call is unlikely and code size would grow
warning: called from here
warning: inlining failed in call to ‘misc_Error’: call is unlikely and code size would grow

I searched about it and compile it with -Winline option. but could not found the solution yet.I am looking for the way to get rid of it.How to get rid of it?

I have posted above problem that I was facing since long before. I am still looking for the solution for it. I tried with removing all the inline from the function. This lead to un-use of many functions defined in the code like:

warning: ‘clause_IsGround’ defined but not used
warning: ‘clause_IsEmptyClause’ defined but not used
warning: ‘clause_LiteralIsFromConstraint’ defined but not used
warning: ‘clause_LiteralIsFromAntecedent’ defined but not used
warning: ‘clause_LiteralIsFromSuccedent’ defined but not used
warning: ‘clause_IsSubsortClause’ defined but not used

I think the removal of inline_ even reduced the performance(speed) of the code.
Can anybody be please suggest some ideas for the above problem?

Answer 1

The compiler thinks that inlining those functions is a bad idea.

The inline keyword is just a suggestion, the compiler doesn't have to follow it. Presumably, the compiler is warning you that it decided to ignore the inline keyword.
