Re: [Ghdl-discuss] GHDL Bug occured for unknown reason

[Lehmann, Patrick]

Hello Simon,

your setup seems to be a bit confusing ...

Your GHDL was compiled with GNAT 5.2.0 and GCC back-end, but the ghdl1 executable is hosted in a GCC 4.9.3. Moreover in an i686 folder (32 bit?).

Many bugfixes have been made since 0.33. Can you compile the latest GHDL 0.34dev from GitHub?

The fastest way it to install GCC, GNAT and LLVM-3.5. Then compile GHDL with llvm back-end. It's faster then GCC and needs not to compile GCC itself.

I have no GCC or LLVM back-ended GHDL at home, but my Windows (mcode back-end) version (0.34dev) reports no errors for your file.

A current LLVM build is also downloadable from https://github.com/Paebbels/ghdl/releases

It was created to test a new deployment process for GHDL. BUT it requires a quite old GCC (4.6 or was it 4.8? - I need to reconfigure the Travis-CI environment to use a newer GCC).

Regards

    Patrick

Betreff: [Ghdl-discuss] GHDL Bug occured for unknown reason

Hello All,

I am using GHDL version
GHDL 0.33 (20150921) [Dunoon edition]
 Compiled with GNAT Version: 5.2.0
 GCC back-end code generator

I got this exception for an unknown reason while compiling a sha256 core from opencores.

ghdl -a --ieee=synopsys -fexplicit -v ../../securehash256bits_org/trunk/sha256.vhd

ghdl: compilation error

VHDL code is attached.

I changed the code from using std_logic unsigned to numeric_std.

Both version exhibit same error.

best regards

Simon
