Add -Xjit:disableCodeAllocationTrimming option - #7677
Merged
Conversation
The codegen typically overestimates the code cache space needed for a compiled method body. However, after the jitted code is generated, the codegen "trims" the initial code cache allocation to the right size. This commit introduces an option to disable such code cache allocation trimming. By default, code cache allocation trimming is enabled, preserving the current behavior. Signed-off-by: Marius Pirvu <mpirvu@ca.ibm.com>
