#7830: Error: operand out of range -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 7.8.1-rc1 Resolution: | Keywords: Operating System: Linux | Architecture: powerpc Type of failure: Installing GHC | Test Case: failed | Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by heisenbug): Replying to [comment:29 erikd]:

I noticed that since the above numbers are using the bootstrap compiler with `-O0`.

As a test, on PowerPC, changed `-O0` to `-O2` which cause the generated assembly file to grow to 302144 lines of code.

At @rwbarton's suggestion added `NOINLINE` pragmas to `above_` and `beside_` functions in `compiler/utils/Pretty.hs` and now the assembler file for `compiler/cmm/PprC.hs` is 158390 lines.

#8901 is a case where adding `NOINLINE` pragmas to the `time` library caused shrinkage in generated `.o` files by a factor ~5. Originally it also busted the 16-bit offsets on PPC32. Not sure whether the `time` maintainer followed my suggestions to add the pragmas or if everybody is just waiting for saner GHC inlining... :-( -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7830#comment:32 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
