2020-11-15x86 hvf cpus: Fix Lesser GPL version numberChetan Pant
There is no "version 2" of the "Lesser" General Public License. It is either "GPL version 2.0" or "Lesser GPL version 2.1". This patch replaces all occurrences of "Lesser GPL version 2" with "Lesser GPL version 2.1" in comment section.

2019-11-26hvf: correctly handle REX prefix in relation to legacy prefixesCameron Esfahani
In real x86 processors, the REX prefix must come after legacy prefixes. REX before legacy is ignored. Update the HVF emulation code to properly handle this. Fix some spelling errors in constants. Fix some decoder table initialization issues found by Coverity.

2019-05-13Normalize header guard symbol definition.Markus Armbruster
We commonly define the header guard symbol without an explicit value. Normalize the exceptions. Done with scripts/clean-header-guards.pl.

2018-10-19i386: hvf: Fix register refs if REX is presentRoman Bolshakov
According to Intel(R)64 and IA-32 Architectures Software Developer's Manual, the following one-byte registers should be fetched when REX prefix is present (sorted by reg encoding index): AL, CL, DL, BL, SPL, BPL, SIL, DIL, R8L - R15L The first 8 are fetched if REX.R is zero, the last 8 if non-zero. The following registers should be fetched for instructions without REX prefix (also sorted by reg encoding index): AL, CL, DL, BL, AH, CH, DH, BH Current emulation code doesn't handle accesses to SPL, BPL, SIL, DIL when REX is present, thefore an instruction 40883e "mov %dil,(%rsi)" is decoded as "mov %bh,(%rsi)". That caused an infinite loop in vp_reset: https://lists.gnu.org/archive/html/qemu-devel/2018-10/msg03293.html Signed-off-by: Roman Bolshakov <r.bolshakov@yadro.com> Message-Id: <20181018134401.44471-1-r.bolshakov@yadro.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
