monitor: Prevent sign-extension of 32-bit addresses printed by info tlb · 94ac5cd2

由 Austin Clements 提交于 8月 21, 2011

This is the same fix that was recently applied to info mem.  Before
this change, info tlb output looked like:

ffffffffffffe000: 000000000fffe000 --------W
fffffffffffff000: 000000000ffff000 --------W

With this change, it looks like

00000000ffffd000: 000000000fffd000 --------W

By always defining these symbols, we can eliminate a lot of ifdefs.

To allow this to be checked reliably, the semantics of the

This allows even more ifdefs to be removed, converting them into

monitor: Prevent sign-extension of 32-bit addresses printed by info mem · b49ca72d

由 Austin Clements 提交于 8月 14, 2011

Previously, on 32-bit i386, info mem used signed 32-bit int's to store
the page table indexes.  As a result, address calculation was done in
32 bits and then incorrectly sign-extended to 64 bits, yielding output
like

ffffffffef000000-ffffffffef031000 0000000000031000 ur-
ffffffffef7bc000-ffffffffef7bd000 0000000000001000 urw
ffffffffef7bd000-ffffffffef7be000 0000000000001000 ur-

This makes these indexes unsigned, which yields correct output

00000000ef000000-00000000ef031000 0000000000031000 ur-
00000000ef7bc000-00000000ef7bd000 0000000000001000 urw

Fix conversions from pointer to tcg_target_long · 3feaca9e

由 Stefan Weil 提交于 7月 15, 2011

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long.

These changes are needed for build environments where
sizeof(long) != sizeof(void *), especially for w64.

See 4b4a72e5 which fixed the
same issue for the other targets.
