Hi all, I am working with GCC 4.1.1. I need some information on the following
Before emitting a call instruction, i need to check for function attributes. Based on that i need to emit the corresponding call instruction. For that, before emitting the call instruction, i check for the attributes of the called function through the declaration node. tree fn_id, fn_decl; fn_id = get_identifier(name); fn_decl = lookup_name(fn_id); This code works fine if none of the optimizations are enabled. But this fails for all levels of optimization as i am not able to get the function decl tree(lookup_name return NULL). When compiling the code with -fno-funit-at-a-time switch, i am able to get the function declaration node. The ASTs are converted into the SSA and eventually to the RTL representations after parsing each function (O0 - No optimization )or when the whole file is parsed (with optimization). When the whole file is parsed, is it that the Function declaration nodes are removed intentionally by GCC ? In this context (with -funit-at-a-time), how will i be able to access the function declaration node of the called function just before emitting the assembly ? Or should i save the function declaration nodes for further use? can any one suggest a workaround!! Thanks in advance, Regards, Rohit
