[LLVMdev] Important change to LLVM makefiles
Please read this if you're working out of LLVM CVS:
I just checked in a change to the makefiles to stop using -fshort-enum
when building LLVM. This flag enables a trivial optimization, but causes
the code generated by the G++ compiler to not match the standard C++ ABI.
Because of this, the presence of the flag makes it more difficult to link
LLVM libraries to external source bases, and it

[LLVMdev] question about gccld and external libraries
hi,
I'm really new to llvm. I've successfully bootstrapped llvm-14 on my
system and am able to successfully compile c code to llvm.
the problem is now that gccld is complaining that it can't find the
libraries, like "c" or "crtend". [1]
all is fine, if I just use intrinsified functions like printf and
friends, but I want to use the clock_gettime function and

[LLVMdev] pass position
Suppose, I have a Pass1 implemented as a subclass of Pass, with source code in
the directory of llvm source base( transform/analyze )
I can run that pass through opt on the bytecode emitted by gcc frontend
through opt tool. However, I want that Pass1 to be the part of the actual GCC
compiler. I want to know how I can position Pass1 among other passes

[LLVMdev] External function 'pthread_once' could not be resolved
Hi LLVM'ers,
I'm trying to build the DotGNU project with the LLVM-tools.
After minor modifications of source and build code and some configure
housekeeping, it seems that I've managed so far to build all the DotGNU
tools. However, when extensively using the DotGNU tools I get this error

[LLVMdev] LLVM IR immediately from frontend
Perhaps I am missing some link. Need a bit clarification.
For the C language,
I want to access the LLVM code immediately generated by
llvmgcc(cfrontend/bin/gcc) before it undergoes any further transformation or
optimization.
1) Are there any libraries that enable me to parse C code and create the
Module instance.
2) If answer to 1) is no, then is there some other way to create Module

[LLVMdev] Compiling natively vsftp with LLVM
Hi,
I am using LLVM to compile vsftp to native x86 ELF code.
One of it's object file (sysdeputil) contains inline asm so cannot be compiled by gcc-3.4 frontend.
So I decided to firstly link together the llvm objects and libcrtend and compile it to native .o file and then link it with sysdeputil.o .
The Makefile is sth like this:
vsftpd: $(OBJS)
gccld -r -native -o vsftpd.o $(OBJS)

[LLVMdev] A small doubt
Hi LLVMDev,
The GCC frontend for LLVM inserts a call to a __main() in the
main() function. Whats the purpose of this? And which LLVM
library do I need to link to satisfy the reference?

[LLVMdev] unoptimised LLVM, not in SSA form
Hi,
I am interested in obtaining LLVM IR without any optimization performed on
it.( IR obtained from cfrontend's AST). Is this LLVM IR in SSA form?
Secondly, I want to make a transformation on this unoptimized IR, and convert
it back to C. I believe llc -c does that.
Thirdly, is it possible to use LLVM tool suite on LLVM IR that's not in SSA
form, if we have such LLVM so.
