D is very good,I like LDC,but it's not use on Raspberry Pi,I hope D will have a great development in Raspberry Pi. Now,I only work on GDC for Raspberry Pi. Will you don't like LDC work on Raspberry Pi? Thank you. |

Hi FrankLike!
Please, could you tell us what you are missing?
LDC has support for Linux/ARM builtin. You should be able to compile on or cross-compile for the Raspberry Pi.
Regards,
Kai

Debian ldc2 package will be uploaded soon (actually it's ldc not ldc2).

The existing package has a useless ldc. Here is the current state of things. I updated my Pi to Jessie, did apt-get ldc which gives: LDC - the LLVM D compiler (0.14.0): based on DMD v2.065 and LLVM 3.5.0 A simple hello world program ends in: _Unwind_RaiseException failed with reason code: -1090604416 Aborted Not too suprising with version 0.14.0. There have been much exception handling improvements since then. -- Dan |

Posted in reply to Dan Olson | Quick status of LDC on Pi. I made a build of ldc master on Raspbian Jessie against LLVM 3.5 available with apt-get. Everything builds ok, but there are runtime problems. Both Fibers and exceptions cause SEGV.
At least now I have a working and up-to-date Pi dev environment.

Ironically, Fibers do work with optimize compile. Something does wrong with -O0, some bad codegen in spots. Simple phobos hello world works, just make sure you give -O to enable optimizer. pi@raspberrypi:~ $ cat hellod.d import std.stdio; void main() { writeln("hi"); } pi@raspberrypi:~ $ /mnt/usbhd/ldc-dev/build-llvm35/bin/ldc2 -O hellod.d pi@raspberrypi:~ $ ./hellod hi pi@raspberrypi:~ $ /mnt/usbhd/ldc-dev/build-llvm35/bin/ldc2 -version LDC - the LLVM D compiler (f94c34): based on DMD v2.068.2 and LLVM 3.5.0 Default target: arm-unknown-linux-gnueabihf Host CPU: arm1176jz-s http://dlang.org - http://wiki.dlang.org/LDC Registered Targets: aarch64 - AArch64 (little endian) aarch64_be - AArch64 (big endian) arm - ARM arm64 - AArch64 (little endian) arm64_be - AArch64 (big endian) armeb - ARM (big endian) cpp - C++ backend hexagon - Hexagon mips - Mips mips64 - Mips64 [experimental] mips64el - Mips64el [experimental] mipsel - Mipsel msp430 - MSP430 [experimental] nvptx - NVIDIA PTX 32-bit nvptx64 - NVIDIA PTX 64-bit ppc32 - PowerPC 32 ppc64 - PowerPC 64 ppc64le - PowerPC 64 LE r600 - AMD GPUs HD2XXX-HD6XXX sparc - Sparc sparcv9 - Sparc V9 systemz - SystemZ thumb - Thumb thumbeb - Thumb (big endian) x86 - 32-bit X86: Pentium-Pro and above x86-64 - 64-bit X86: EM64T and AMD64 xcore - XCore |

I am assuming that very few folks are trying LDC with target arm-unknown-linux-gnueabihf because LLVM really has a problem with simple global variables (__gshared). It is not LDC, but LLVM. The codegen to load a simple global variable is all wrong with optimizer disabled (-O0). // load x into a register ldr r0, .LCPI0_0 ldr r0, [r0] ldr r0, [r0] // what?! an extra load? SEGV! // elsewhere, x is defined as x: .long 0 .LCPI0_0: .long x Clang is ok at -O0. But if I take clang IR output (-emit-llvm) and generate code with llc -O0, it too has extra ldr instruction. Clang must be adding some optimization passes at -O0 that are different than llc -O0. I think LDC uses same passes as llc, so there is the problem. Next, see if LLVM has a bug filed for this and find that extra optimization pass for LDC. -- Dan |
