--- Comment #3 from Martin Jambor <jamborm at gcc dot gnu.org> --- Author: jamborm Date: Tue Sep 24 11:20:57 2019 New Revision: 276094 URL: https://gcc.gnu.org/viewcvs?rev=276094&root=gcc&view=rev Log: [PR 91831] Copy PARM_DECLs of artificial thunks Hi, I am quite surprised I did not catch this before but the new ipa-param-manipulation does not copy PARM_DECLs when creating artificial thinks (I think it originally did but then I somehow removed during one cleanups). Fixed by adding the capability at the natural place. It is triggered whenever context of the PARM_DECL that is just taken from the original function does not match the target fndecl rather than by some constructor parameter because in such situation it is always the correct thing to do. Bootstrapped and tested on x86_64-linux. OK for trunk? Thanks, Martin 2019-09-24 Martin Jambor <mjam...@suse.cz> PR ipa/91831 * ipa-param-manipulation.c (carry_over_param): Make a method of ipa_param_body_adjustments, remove now unnecessary argument.
