- Subject: Register Usage - RTL Expression
Hi all,
I am working with GCC Cross compiler 4.1.1. I just some information
regarding the following:
1. How does the life1 pass gets the register usage information from
the gcse pass?
2. From which other passes and how, the information about registers
used can be determined by looking at the RTL dump of the corresponding
pass?
3. Any documentation regarding the above?
Regards,
Rohit
