Hello all - I ran into and then solved a very weird error in which the symtab_section global variable is being set to some non-null value during the constructor phase of my compiler state, but is null when I actually try to add symbols! The reason is because the symbol addition occurred from a different .so file as the constructor, and these apparently did not share their global symtab_section global variable.
Obviously, my understanding of dynamic linking is weak, but bear with me, I have a sensible question: Is there a good reason symtab_section is a global variable? In addition to the issue that I encountered, what if I want to have multiple compiler states? It looks to me like the pointer for symtab_section will be overwritten for each call to the constructor. Won't this lead to trouble? And is there any reason we don't have a field in the TCCState struct to store the location of symtab_section? Thanks!
