objc object file generated for gnustep runtime for ELF target is too big
Dear community,
I'm using gnustep runtime -fobjc-runtime=gnustep with gnustep-libobjc2 (https://github.com/gnustep/libobjc2) and
Cocotron/Chameleon.
For following source file
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
int main(void)
{
NSString *str = [NSString stringWithCString:"TEST"];

[LLVMdev] question about alignment of structures on the stack (arm 32)
...#39;s odd ).
Sorry I didn't clearly described my environment.
I'm using MachO loader (https://github.com/LubosD/darling/). I'm trying to make it work on ARM.
The scenario is to load MachO binary (e.g. compiled in xCode) that binary is invoking function from
ELF library which implements libobjc2 and CoreFoundation.
in MachO on the ARM stack is 4-bytes aligned. Code produced for ELF expects 8-bytes alignment.
So in 50% cases when call made from MachO to ELF stack pointer register contains not a 8-bytes aligned address.
Even in case of trivial call

[LLVMdev] Treatment of TType encoding in EHT entries
Hi,
I ran into a crash using Objective-C with llvm/clang on ARM-Linux. The
crash happens while unwinding the stack from pthread_exit as soon as the
first call frame is reached that belongs to a function that uses the
personality routine from libobjc2.
This function is in a shared library (libgnustepbase), and here's the
start of its entry in the execption table:
GCC_except_table20:
.Lexception20:
.byte 255 @ @LPStart Encoding = omit
.byte 0 @ @TType Encoding = absptr...

Building clang in llvm-3.7 on Linux with RT support enabled
> Unfortunately you’ll need to either modify the LLVM build system to build it, or you’ll need to build it yourself by hand. We don’t currently support building the blocks runtime.
Thanks! I'm working on a modified build now.
Out of curiosity: is cmake still the preferred way to build on Linux? You mentioned that the doc is out-of-date, so I thought perhaps there might be a newer way to

[LLVMdev] question about alignment of structures on the stack (arm 32)
Dear community,
I faced with code which was generated by llvm, assembly instructions of that code is relying on 8-bytes alignment for structures on the stack.
The part of Objective C code is following:
-(void)getCharacters:(unichar *)unicode {
NSRange range;
range.location = 0;
range.length = [self length];
printf("%p, %p\n", &range.location, &range.length);
And

Building llvm with clang and lld on arm and the llvm arm backend relocation on position independent code
At a guess that looks like your llvm and lld checkouts are not quite
in synch. It will be worth updating llvm and lld to top of trunk.
I've rebased the consolidated patch https://reviews.llvm.org/D34634
this morning, it might be worth trying that if you are seeing
problems.
