Re: AST in GCC

Again while generating assembly code, what kind of information it is dirrectly getting from the ASTree and others from the RTL file ?? and which function is used in GCC source code to directly dump values from AST to assembly code.

#Thanks a lot,
#        Again if I am going to next levels of passes in gcc it is creating
#different forms of RTLs. I can check the RTL files with -dr, -dP, -dK
#options. Where -dr option gives the first level RTL form.

Just for your info, there are many more options. Check the documentation
or dig the code.

#      Is the AST required for getting each level of RTL or it is required
#for first level of RTL generation only and subsequent steps are generated
#basing upon the first level??

Later is correct.

Warm regards
