So which compiler is generating the bogus code here? Is this the stage1 x86-64 compiler, or the i386 compiler? It's the stage1 x86_64 compiler. The problem here is that 37590000000000174587920 doesn't even fit into 64 bits, hence the assembler's complaint.
Yes, I see that. GHC keeps these values as Integers internally, so it's possible that some misconfiguration has caused it to produce a values that's out of range, although I agree that the fact that it is bigger than even 2^64 is quite suspicious. I suggest dumping out some intermediate code, e.g. -dppr-cmm -dppr-opt-cmm. If that fails to narrow it down, then you may need to add some debug traces the native code generator to find out where these values are coming from. Cheers, Simon
