[LLVMdev] Problems with void*
...o use the LLVM classes (with Modules in memory) to represent some programs that use
the void* type but I am having some problems handling that type.
If I use WriteBytecodeToFile, I receive this error:
Assertion `slot != -1 && "Module broken!"`
If I save the module directly with PrintModulePass, it generates the .ll file fine, but if I try
to compile it with llvm-as, as soon as it finds 'void *' it complains that it was expecting an "("
instead of an "*". I suppose that the correct syntax is something like this: 'void (sbyte *)*'
For example, these li...

[LLVMdev] How to place call(s) to functions found in other llvm modules ???
Hi,
I tried this as well, using the following line to add function
declaration to the caller module.
Function::Create(FT, Function::ExternalLinkage, "gcd", mod);
Where "FT" is the same as before. And the output produced by the
PrintModulePass becomes:
; ModuleID = 'GCDMain'
declare i32 @gcd(i32, i32)
define i32 @main() {
EntryBlock:
%tmp = call i32 @gcd(i32 30, i32 50)
ret i32 %tmp
}
But it still fails to WriteBitcodeToFile, and produces the same error as
before.
I guess I might be missing some attribute, like "...

This isn't correct at all, this should return a CGSCCPass as a printer. Adding a Module pass will change the ordering of passes in the passmanager, which will cause your option to completely change behavior of the optimization sequence.

[LLVMdev] code generation goes into an infinite loop
...nt the simplest possible code generation. Specifically, we are
trying to emit code for the following program, as it is easily
testable from the command-line:
int main(int argc) { return argc; }
We got our code generator to build and link with llvm. When we run
it, it pauses when running the PrintModulePass and then exits with a
bus error. I suspect that this is an infinite loop leading to a stack
overflow.
While many kinds of errors we could fix by looking at other people's
examples or reading the docs, I suspect that this should be considered
to be a bug in the verifier pass: clearly we genera...

Good point! It is very likely that PrintMIRPass could be implemented with (4) above.
For AsmPrinter's uses of ` doInitialization`, I'm not 100% sure. It looks like it could also be replaced by (4).
But difference is ` doInitialization` is invoked before all passes `run` method, whereas (...

The potential benefits using NPM aside, this inhibits us from making any progress on deprecating LPM for the codegen pipeline which blocks
