Change History (most recent first):
|
|||
|
|
|
|||
|
|
<1> 12/7/92 DRF first checked in
|
|||
|
|
<7> 12/7/92 DRF Change inline glue for Get/SetNativeFPRs to use 16-bit inline
|
|||
|
|
hex, instead of the nice 32-bit constants. The compiler was only
|
|||
|
|
using the low 16-bits of each constant!
|
|||
|
|
<6> 12/4/92 DRF Changed names of Get/SetFPRs to Get/SetNativeFPRs
|
|||
|
|
<4> 11/9/92 JCM Fix typo in kSetFPRSelector
|
|||
|
|
<3> 11/9/92 DRF Added GetFPRs() and SetFPRs() so that the Process Manager can
|
|||
|
|
get and set the preserved native floating point registers
|
|||
|
|
(fpr14-fpr31). NOTE: We only compile this in for the mac-based
|
|||
|
|
compiler.
|
|||
|
|
<2> 10/12/92 EPT Added macros OSTrapTableAddress and TBTrapTableAddress.
|
|||
|
|
<3> 9/19/92 LC Add declarations of entry point names.
|
|||
|
|
<2> 9/9/92 LC Moved some private definitions to MixedMode.h so that a user can
|
|||
|
|
use the macro "BuildRoutineDescriptor"
|
|||
|
|
<1> 9/1/92 BKJ first checked in
|
|||
|
|
8/28/92 BKJ change to reflect latest ERS
|
|||
|
|
6/2/92 BKJ first checked in
|
|||
|
|
4/20/92 BKJ First Created
