Dear developers, We found the following comment in VEX/priv/host_ppc_defs.c, lines 107-109: /* Don't waste the reg-allocs's time trawling through zillions of FP registers - they mostly will never be used. We'll tolerate the occasional extra spill instead. */ Is this comment still valid - that is, is the register allocator susceptible for a high number of allocatable registers? I went quickly through the register allocator code in doRegisterAllocation() but could not find anything relevant. Thank you for any insight here, I. |
