Do some refactoring so that the code can be inlined by the C1/C2 optimizer.
1. DirectClassBuilder::build codeSize 361 -> 315 2. DirectCodeBuilder::writeExceptionHandlers codeSize 183 -> 31 3. BufWriterImpl::writeIndex codeSize 62 -> 37 (forceinline) 4. BufWriterImpl::writeU2 (forceinline) 5. Util::writeAttributes codSize 45 -> 40 (forceinline) 6. Util::writeList codSize 47 -> 42 (forceinline) ------------- Commit messages: - inline writeLong & local constantPool - fix write header - suggestion from @liach - force inline Util::writeAttributes & Util::writeList - force inline writeU2 - force inline invalidIndex - optimize for writeExceptionHandlers for C1 - optimize DirectClassBuilder::build Changes: https://git.openjdk.org/jdk/pull/21118/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=21118&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8340710 Stats: 50 lines in 4 files changed: 31 ins; 6 del; 13 mod Patch: https://git.openjdk.org/jdk/pull/21118.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/21118/head:pull/21118 PR: https://git.openjdk.org/jdk/pull/21118
