JDK-8204240 - Extend MDO to allow more reasons to be recorded per bci
Description
Today we only record uncommon traps taken for the first 7 Reasons. On 64-bit VMs the field (_header) in MDO DataLayout is already an intptr_t (64-bit on 64-bit VM) but we only use 32. For 32-bit VMs we need to extend the field.
Comments
Actually my fix only extends space dedicated to reasons but it doesn't change all reasons to be per bci. Assigning that back to Rickard.
