Re: What is QRArch used for?

So what's the difference between ARM5T and ARM4T? Under what circumstance
that I need to override the ARM4T with ARM5T? Does it will benefit the
performance?

Thank you!

ARM_XSCALE_C_CMD_LINE it's used to add command line options to the C
compiler when you are compiling code for Xscale based ARM processor; in your
case, the default option 'compile for ARM 4T architecture' is overridden
with 'compile for ARM 5T architecture'.
If you take a look at %_WINCEROOT%\PUBLIC\COMMON\OAK\MISC\makefile.def file
you can see what the several 'sources' file directives mean.

When I compile my BSP, some of this warning message shows up:
cl : Command line warning D4025 : overriding '/QRarch4T' with '/QRarch5T'

And then I found that in the source folder, the makefile added a new line
like this:
ARM_XSCALE_C_CMD_LINE=-QRarch5T

Can somebody tell me what it is used for, and when to use this option?
Besides that I cannot find ARM_XSCALE_C_CMD_LINE in MSDN, where it was
defined?
