|Jikes RVM 2.1.1 is now available from the developerworks web site. |
The main purpose of this release is bug fixes.
IMPORTANT NOTE: We are aware of a bug in the IBM DK for
Linux/IA32 v1.3.1 when building Jikes RVM. Stick with
version v1.3.0 until this bug can be resolved.
Highlights of this release include:
- Introduction of a new method-level runtime exception
pragma mechanism, contributed by Chapman Flack. The
system now relies on this mechanism for method-level
pragmas for uninterruptibility and inlining directives.
- Restructuring of baseline compiler to increase the
amount of platform-independent shared code.
- Stricter enforcement of uninterruptibility rules.
- Improvements to SSA optimization package to reduce
register pressure. These changes make O2 profitable
for use by the adaptive system on IA32.
- The VM_CompilerInfo classes were folded into the
NOTE: VM_Magic.pragmaInline and VM_Magic.pragmaNoInline
are deprecated, and will not be supported in the 2.1.2
release. Migrate code to use the new runtime exception
