[jira] Created: (HARMONY-5504) [drlvm][port] Restructure DRLVM's
sources to extract most of platform dependent code into portlib
[drlvm][port] Restructure DRLVM's sources to extract most of platform dependent code into portlib
-------------------------------------------------------------------------------------------------
Key: HARMONY-5504
URL: https://issues.apache.org/jira/browse/HARMONY-5504
Project: Harmony
Issue Type: Task
Components: DRLVM
Environment: All
Reporter: Gregory Shimansky
Assignee: Gregory Shimansky
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.

Ilya Berezhniuk commented on HARMONY-5504:
------------------------------------------
I suggest closing the issue; most part of restructuring is done.
Remaining part (moving guard page operations to the Port) should be done in HARMONY-5617.

-------------------------------------
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

[jira] Updated: (HARMONY-5504) [drlvm][port] Restructure DRLVM's
sources to extract most of platform dependent code into portlib
Posted by "Ilya Berezhniuk (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HARMONY-5504?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ilya Berezhniuk updated HARMONY-5504:
-------------------------------------
Attachment: 0012-Implemented-universal-transfer-control-stubs-in-PORT-a-part-of-hythread-was-moved-to-PORT.txt
0011-move-Moved-files-responsible-for-context-conversion-and-C-handler-args-preparation.txt
Adding '0011' and '0012' patches.
These patches move to the portlib a part of hythread functionality, register context conversion from VM core, and significantly modifies a scheme of signals/exceptions processing.
The main change is the following.
Earlier signals/exceptions handlers pushed required arguments for C-language handlers to stack/registers, and used transfer control stub to go to the C handler. This C handler also used transfer control stub to go to the modified register context after signal/exception processing. The transfer control stub used JIT context from the stack iterator for restoring processor registers.
This patch introduces universal transfer control stub which uses Registers structure for restoring context. (The stubs are in portlib and written in assembler. It would be better to rewrite them in encoder - now VM provides executable memory for encoding.)
Another one function introduced is a function for preparing register context for calling C handlers.
This function receives variable arguments number: C-handler address to be called, Registers pointer and up to 6 C-handler arguments.
Initial register context is stored to the appropriate stack area, and registers are modified to call C handler.
Address to return from C handler is set to small assembler stub which calls transfer control stub with saved register context - so C handler returns to the interrupted code.
Additional useful feature is provided: when the first argument for C handler is the same Registers pointer as fixed argument, then C handler receives an address of Registers structure saved on the stack as a first argument. So all modifications made by C handler in these Registers will take effect after returning from C handler.

-------------------------------------
Attachment: 0003-corrected-build-for-moved-LIL.txt
0002-move-moved-LIL-files-from-PORT-to-VMCORE.txt
Gregory,
I suggest moving onoly VM and Java independent code to port.
I also suggest moving Java or VM-dependent code away from port.
The following two patches move LIL implementation from port to VM core - it's built with VM core anyway.
The first patch is for moving/renaming files; the second one is a patch for adoption.

Patch 0013 committed at 633477.
Now that all patches queue from this JIRA is integrated I suggest that we create subtasks for individual patches. The number of comments gets quite big for just one.

> 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.
