Hello all,
I'm trying to get ghdl hg813 to work with llvm 3.6.
There are two problems compiling the compiler:
- replaceOperandWith now takes a Metadata * instead of Value *
- LinkInJIT no longer exists (and was a nop already in 3.5)
I applied the attached patch, which allowed me to build the compiler
binary. However, when trying to compile the standard library, the
compiler crashes.
ghdl1-llvm -g --std=87 --bootstrap --work=std -c -o textio.o
../../src/std/textio.v87
Program received signal SIGSEGV, Segmentation fault.

Does anyone have an idea what's wrong here?
