[LLVMdev] crtend
Before upgrading to the latest LLVM today, I used to run the following
command:
llvm-gcc -fno-inline -o __tmp.homer___ llvmtest/sliceme2.bc
-L/home/testbed1/lefever/work/llvm/install/lib -lcrtend
However, it is given the following error.
/usr/bin/ld: cannot find -lcrtend
collect2: ld returned 1 exit status
make: *** [llvmtest/sliceme2.cbc] Error 1
Has the crtend library been moved?
Thanks,

__main() is used to run static constructors and destructors, so if
you're compiling without -c, LLVM knows all the files

Robert,
Thanks for the info, you've confirmed what I was trying to do, but when
I compile:
-----------------------
#include <stdio.h>
int main(int argc, char *argv[])
{
printf("yo\n");
return 0;
}

without "-c" (llvm-gcc t1.c -o t1) the dissassembled bytecode does not
call __main:

[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?
Thanks,
Rahul

[LLVMdev] Building the llvm runtime: 'Can't destroy file: The process cannot access the fi
Hi Jeff and others,
When building the llvm runtime, I always get this error message: 'Can't
destroy file: The process cannot access the file because it is being used by
another process.' The file is destoyed anyway.
I think that the the real error is the path for the file (*/\file.tmp).
However, I can't find the bug in the source. Do you have any clue?:

[LLVMdev] Building the llvm runtime: 'Can't destroy file: The process cannot access the fi
It looks like what you're getting is a sharing violation. Although, I
don't understand why. The llvm-ar.exe when its building an archive file
always builds it in a temporary. Only when that is complete does it
remove the old one and rename the temporary. Perhaps this is a result of
doing parallel build and the "lib3.tmp" file (that name looks wrong to
me) is being accessed by
