This clean-up improves consistency within i386.md by using QImode for the constant shift count in patterns that specify a mode.
This patch has been tested on x86_64-pc-linux-gnu with make bootstrap and make -k check, both with and without --target_board=unix{-m32} with no new failures. Ok for mainline? 2023-06-18 Roger Sayle <ro...@nextmovesoftware.com> gcc/ChangeLog * config/i386/i386.md (*concat<mode><dwi>3_1): Use QImode for the immediate constant shift count. (*concat<mode><dwi>3_2): Likewise. (*concat<mode><dwi>3_3): Likewise. (*concat<mode><dwi>3_4): Likewise. (*concat<mode><dwi>3_5): Likewise. (*concat<mode><dwi>3_6): Likewise. Thanks, Roger --
