os_data_hdr Struct Reference
[Advanced Features and Debugging]

#include <tr_debug.h>

Detailed Description

A representation of the debug header data.

TiROS does not use this structure directly. This is presented here to illustrate the type of debug data that TiROS encodes.

unsigned char os_data_hdr::os_options

Byte 1: Options.

RegisterPassing, ExtraDebugging, 

	     Reserved -      4 bit.
	     prio_sort_method - 2 bits  -- 00 - not included.
	                                   01 - method = 1
	                                   10 - method = 2
	                                   11 - method = 3
	     RegisterPassing - 1 bit.

unsigned char os_data_hdr::data_sizes1

Byte 2: Data Type sizes 1.

Data type sizes are either 8,16,32,64 bits. Any value in between (for ex. 24 bits) is padded up to the next highest value. 

	  tid_t size  - 2 bits: 8, 16, 32, 64 bits.
	  subtime_t size - 2 bits: 8, 16, 32, 64 bits.
	  flag_t size    - 2 bits: 8, 16, 32, 64 bits. 
	  osword_t size - 2bits
