[jira] Commented: (HARMONY-3065) [DRLVM][hy_thr] Force inline of
p_TLS_vmthread and tmn_suspent_enable/disable.
[ https://issues.apache.org/jira/browse/HARMONY-3065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12477551 ]
Rana Dasgupta commented on HARMONY-3065:
----------------------------------------
1)
>mov ax, [edx]HyThread.suspend_disable_count
>dec eax
>test eax, eax
right, that's a typo' ...good catch
movzx eax, [edx]HyThread.suspend_disable_count //disable_count is 16 bits
2)
>like "mov ECX, [EBP]-12".... Can the following lines simply be deleted?
no locals, so frame setup not needed
>push ebp
>mov ebp, esp
>move esp, ebp
>pop ebp
it is just preference, i like saving esp in a native call because I don't know what conventions I will call out into. In this case, you can remove these, but then you will need to uncomment "pop edx" after calling thread_safe_point_impl
