    Description

      Similar to JDK-8255838, it would be useful to shorten movptr(reg, imm) when immediate fits in 32 bits. This would compact some code, notably the code in C1 profiling (JDK-8315843), but also other code, generically.

      Early prototype shows 1% code saved for C1 tier3 and C2 tier4.
