From: Sunil Dora <[email protected]>
The generated CompletionModel.cpp overflows 16-bit branch displacements
on ppc32 and the assembler rejects it with thousands of
{standard input}:177591: Error: operand out of range (0x81f8 is not
between 0xffffffffffff8000 and 0x7fff)
Build clangd with -DCLANGD_DECISION_FOREST=OFF on powerpc, which falls
back to the heuristic completion ranking.
