I have recenty updated my LDC to the most recent version
(1.14). The problem is that it compiles to LLVM code version
7.0.1, but I need it to compile to LLVM 6.x.x or LLVM 5.x.x.
The last release note said that LLVM versions from
3.something.something are supported, but does this mean only
linking to them, or also compiling to them?
If it can be done, how? Thanks.
Do you mean bitcode, LLVM IR or something different? The LDC
built against a given version of LLVM can link to bitcode/compile
LLMV IR, of that version.
Lowest LLVM it can be compiled against is 3.9. LDC's releases are
compiled against 7.0.1, but that doesn't stop you downloading a
release of the desired LLVM version and compiling LDC against
that.
All you need is a semi-recent CMake. Just git clone from our
github and run cmake, you'll need to provide the location of the
llvm-config binary as LLVM_CONFIG but thats it.
