Question about supporting aot on other platforms (RISC-V)
by Hamlin Li 18 Jul '25

18 Jul '25

Hi, I'm trying to apply changes related to aot on riscv (first step is https://github.com/openjdk/jdk/pull/26101, also plan to apply further changes in the future gradually). As Andrew suggested in the pr, there will be more changes (especially related to code save/restore) from leyden premain to mainline. I went through the pr's and discussion of leyden, found out several changes might be platform related: 1. Store cpu features in AOTCodeCache header ( https://github.com/openjdk/leyden/pull/84 ) (Open) 2. AOT code generation should support UseCompactObjectHeaders ( https://github.com/openjdk/leyden/pull/78 ) (committed into premain) I think in the short future, these above pr's are going to get into mainline. But I might overlook some pr's or discussions, Besides of these above pr's, are there any other potential changes or discussions I should pay attention to when I try to support aot on riscv? I asked the questions to make sure after I integrate https://github.com/openjdk/jdk/pull/26101, even if more leyden changes are merged (including the above ones) into mainline, I can still make aot work as expected on riscv quickly, rather than break aot things for a long time, i.e. hope no surprise in the progress. Thank you -Hamlin
