Attempt for rotating register allocation

the back-end of GCC. Needs advice and cooperations. Chunjiang Li Creative Compiler Research Group, National University of Defense Technology, China.

Re: Doubt about Pseudo register uses.

Thx. I also guessed that. But, for I am a rookie in GCC, I know little about GCC, need advice. Ian Lance Taylor : > Chunjiang Li <[EMAIL PROTECTED]> writes: > > > I wonder is it true that one Pseudo register is only corresponding to one > basic block? > > No, i

Also about the Pseudo reg usage problem.

Hi, all: Also the problem about Pseudo register usage. I want to know the Pseudo registers used (def and ref) in a basic block. How can I get these result using the APIs presented in GCC? Need help. Urgently. May be need to refer the df.c and df.h interface, but I am not sure. Chunjiang Li

Doubt about Pseudo register uses.

Hi, all, When I read the GCC source code about register allocation, I wonder is it true that one Pseudo register is only corresponding to one basic block? the reg_info struct is: typedef struct reg_info_def { /* fields set by reg_scan */ int first_uid;
