[Qemu-devel] [PATCH] Fix symbol lookup for mips64* targets

[Stefan Weil <weil@mail.berlios.de>]

[-- Attachment #1: Type: text/plain, Size: 454 bytes --]

For 64 bit targets, lookup_symbol() compares a 64-bit target address
with a 32 bit symbol address. This only works for addresses less than 2^32.

MIPS64 kernels use addresses larger than 0xffffffff80000000,
so qemu.log never shows symbolic names.

My patch is a workaround which works with Qemu's 32 bit address hack.
Please apply it to Qemu trunk.

Maybe a better solution would use symbol addresses without shortening
them to 32 bits.

Regards
Stefan
