Avoid "boot" in xv6
2011-08-15 20:11:13 -04:00
c60a3551c2
Separate more clearly bootloader from xv6 by renaming multiboot.S to entry.S etc.
...
Maybe the string boot shouldn't appear in xv6 code?

Add -fno-omit-frame-pointer to compile flags.
...
At some point between gcc 4.4 and 4.6, omitting the frame pointer
became default if any -O is specified. getcallerpcs relies on the
frame pointer, so bring it back.

Fix for gdbstub argument change in qemu 0.11. Rename qemu-gdb-nox target to qemu-nox-gdb because you frequently want to add the gdb part, but rarely the nox part.

this time do it ourselves instead of piggybacking on TLS.

Some proc cleanup, moving some of copyproc into allocproc.
