similar to: [LLVMdev] Finding the functions whose addresses are taken.

Each function is a GlobalValue. Find all the uses of them... any uses that are not a "call" with the function as callee goes into your list. Global variables work the same way. Find the uses of them that are not "Load" or "Store" instructions with the global value as the pointer operand. On Tue, Sep 8, 2009 at 12:20 PM, Sanjiv Gupta<sanjiv.gupta at

Hi, Apparently, there is no explicit support for ISRs in the llvm framework. I could not find a matching attribute that can be used to mark a function as an ISR, which codegen and optimizer can use accordingly. ISRs aren't called explicity from any function, so currently the optimizer deletes them. We are planning to introduce a new "interrupt" attribute (to be modeled similiar to

Hi Mikhail, Thanks for your wonderful help so far. I have few more questions to ask: How do I modify the driver to pick tools from where the driver itself resides, rather than from the PATH? And how to make sure that we have same behavior on Windows as far as paths (/ Vs \) and picking up tools from the driver directory is concerned? Do I need to write some C++ code to customize such

Consider the example command line below $ llvm-ld -disable-opt hello.bc -l std -o hello.out Why does -disable-opt links in all the bitcode from the libstd.so into hello.out? - Sanjiv

It doesn't matter in terms of semantics: because AnalyzeGlobal returned false, we're guaranteed the address of the global is never taken. I wouldn't be surprised if we end up generating invalid IR in some cases,

The code excerpt is from IPO/GlobalOpt.cpp // If this is a first class global and has only one accessing function // and this function is main (which we know is not recursive we can make // this global a local variable) we replace the global with a local alloca // in this function. // // NOTE: It doesn't make sense to promote non single-value types since we // are
