Subject [jira] Updated: (HARMONY-5504) [drlvm][port] Restructure DRLVM's sources to extract most of platform dependent code into portlib
Date Thu, 21 Feb 2008 18:05:19 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-5504?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ilya Berezhniuk updated HARMONY-5504:
-------------------------------------

    Attachment: 0010-PORT-thread-basic-implementation.txt
                0009-move-Renamed-apr_thread_ext.h-to-port_thread.h.txt

'0009' and '0010' patches add transfer_to_regs() function for future use in PORT signal handlers.

Additional changes include:
apr_memory_rw_barrier is replaced with port_rw_barrier
removed unused port/src/thread/**/apr_thread_ext.c
JVMTI control transfers are switched from si_transfer_control to new transfer_to_regs() function
Current x86/x86_64 transfer control stubs in VM are slightly modified

> There is a code freeze, so I decided to create a working place for my patches for DLRVM's
port library in JIRA.
> The goal of this task is to separate DRLVM's platform dependent code from VM sources
into multiple subcategories of port library. Such platform dependent code is crash handler,
stack iteration, signals/exception handlers, modules tables, NCAI safe memory access and probably
some more stuff that I didn't identify yet.
> Such separation will define clear interfaces, possibly some components could be reused
by other projects.
