10.8.3.4 restrictions
The following shows the restrictions for measurements.
・ Valid profiles cannot be obtained if the function name labels in assembler sources do not also have stab
information using ".type."
Example) .type sub, @function
This is also required when creating a library.
* The above is not necessary for C sources because the C compiler automatically outputs ".type" statements.
・ Valid profiles cannot be obtained if the program counter (% PC) is forcibly changed using "set $pc = XXX" or
similar means while the program is in break mode.
・ Valid profiles cannot be obtained if a measurement is interrupted̶for example, executing the "c17 pro-
filemd 0" command while the program is in break mode, executing the program again, and then executing the
program once more after executing the "c17 profilemd 1" command in break mode.
・The measurement range can be from RESET (boot address) to the address at which a break occurs.
It is not possible to perform measurements in a range from a specific address to the address at which a break
occurs. However, measurement will continue until the subsequent break even if "Go" is executed again without
changing "%PC" after a break.
・ A profile cannot be obtained from a program that transfers a program or function dynamically from the ROM
area to the RAM area and executes it (e.g., programs in which ".text" sessions are linked as LMA ≠ VMA).
・ A profile cannot be obtained if a program has more than 10,000 functions and made more than 10,000 calls.
・ A profile cannot be obtained if a program made more than 10,000 deep calls as viewed from RESET (boot
address).
・ Static functions without debug information (without assembler −gstabs option or compiler −gstabs option)
cannot be displayed in the form of "function name + @ + filename"; the filename section will not be displayed.
