modification history
|

--------------------
|
||||
01v,20may16,jmp Imported from vxWorks 7 for WB4 debug support:
|
||||
Added 8 bytes hardware breakpoint support (US11680).
|
||||
Added VXDBG_HAS_HW_BP_SUPPORT_CHECK as VxDBG provides support
|
||||
to dynamically detect if HW BP support is enabled on this
|
||||
architecture (US39045).
|
||||
01u,16oct12,scm WIND00376020 - fast system call support...
|
||||
01t,22oct10,jmp Removed obsolete DSM() macro - Replaced by VXDBG_INSTR_CMP().
|
||||
01s,29jul10,pad Moved extern C statement after include statements.
|
||||
01r,19jun09,mze replacing PAD64
|
||||
01q,20mar09,jmp removed DBG_INST_ALIGN definition (Use the default one).
|
||||
01p,10feb09,jb Adding 64-bit Support
|
||||
01p,31mar09,dbt Disable hardware breakpoint support for Hypervisor
|
||||
Guest OS (CQ:WIND00161733).
|
||||
01o,16feb05,aeg changed wdbDbgCtxXXX() prototypes (SPR #106381).
|
||||
01n,14oct04,elg Rename wdbDbgCtxXXX() in wdbCtxXXX().
|
||||
01m,01sep04,elg Define context load/save for WDB.
|
||||
01l,19aug04,jb Fix for SPRs 100660, 100729, and 100748
|
||||
01k,25jun04,elg Undefine WDB_CTX_LOAD() to use standard definition
|
||||
(SPR #98730).
|
||||
01j,27apr04,jmp adapted to share trcArchLib between VxSim/i86 and i86 arches.
|
||||
01i,02mar04,jb Adding StepOverSyscall support
|
||||
01h,17jul03,c_c Fixed build.
|
||||
01g,16sep02,pai Updated with commonly used manifest constants.
|
||||
01f,30may02,hdn added WDB_CTX_LOAD() define (spr 75694)
|
||||
01e,11mar98,dbt corrected problems introduced by the SENS merge
|
||||
added Copyright.
|
||||
01d,13feb98,hdn fixed BRK_DATAxx macros.
|
||||
01d,30dec97,dbt modified and added some defines for new breakpoint scheme.
|
||||
01c,29nov93,hdn added a definition EDI - EFLAGS.
|
||||
01b,27aug93,hdn added support for c++
|
||||
01a,11sep91,hdn written based on TRON version.
