The preprocessor turns a string literal into a CPP_STRING token. The parser turns that into a STRING_CST node in GENERIC. The RTL expander stores the string constant into the constant pool and works with a symbol pointing to the address. This and the various string literal optimizations are scattered across various files. Search for CPP_STRING and STRING_CST to see the kinds of things that gcc does. Ian
