In-Reply-To: Your message of "Tue, 02 Jan 2001 14:39:03 EST." <200101021939.OAA07752@hiauly1.hia.nrc.ca>
= Last time I looked the 64 bit port was still using the same milli
= library as the 32 bit port.
Yes -- leading to some very surprising 64-bit kernel failures
before I found this "feature". This is a 64-bit parisc linux gcc bug.
= Thus to integrate a 64 bit library,
= some work would have to be done to the machine description. There
= are hooks to build asm code (see for example lib1funcs.asm and
= lib2funcs.asm in config/pa).
I've played with this a bit before -- I did the first ELF version of
of 32-bit millicode. But I'm not at all certain we want to
keep millicode in libgcc.a since there's also some parisc linker magic to
automatically link millicode when required -- because some makefiles
using ld -r break (like the Linux kernel build) unless they're hacked to
include an explicit reference to libgcc.a.
= Has HP contributed this code to the public domain? Probably, Jeff
= Law would be the one to contact to get integrated into the gcc mainline.
I have permission to sanitize and (L?)GPLize it. I'm planning to
attempt the basic integration and then let Jeff or someone tell me
how I screwed it up :-)
