This change is also fine.
The gcc.target/hppa/shadd-2.c test now fails because there are two additional sh1add instructions. However, the total number of instructions is the same as before. I confirmed that change fixes PR middle-end/87256. So, we can close this PR when the patch is installed. Please install on trunk and gcc-10. gcc-10 is the default compiler on Debian.
