--------------------
|
||||
01q,01apr10,dbt Removed pc macro to avoid name conflicts (WIND00205750).
|
||||
01p,05jan07,elp moved simStatus and simIntPendingLvl to host,
|
||||
added interrupt level macros.
|
||||
01o,24nov06,dbt Added WIND_CPU_STATE
|
||||
01n,26jul05,jmp added fpReg as defined on other architectures.
|
||||
01m,29dec03,jeg added REG_SET_MMU_TRANS_TBL macro. Added additional macros
|
||||
required for RTP support.
|
||||
01l,01dec03,jmp added mmuTransTbl (current MMU translation table) to REG_SET.
|
||||
01k,24nov03,jeg added macros to manage supervisor bit
|
||||
01j,18sep03,jeg removed SIM_STATUS_INIT macro.
|
||||
01i,09sep03,jeg updated REG_SET structure to split intLockKey by a status
|
||||
bit field.
|
||||
01h,03apr03,dbt Removed references to ucontext.
|
||||
01g,25mar03,dbt Replaced reg_onstack field in TDB with intLockKey.
|
||||
Removed no longer used signal mask from REG_SET.
|
||||
Enabled use of macro in assembly code.
|
||||
01f,20mar03,jeg removed REG_XX definitions
|
||||
01e,18mar03,dbt Added interrupt level in REG_SET.
|
||||
01d,19jun01,jmp used host NGREG if defined.
|
||||
01c,30dec97,dbt added common names for registers
|
||||
01b,27oct95,ism cleanup
|
||||
01a,12jun95,ism written
