Ryan Houdek 6b7d508401 Adds a couple LEA unit tests for 16bit addressing mode 2021-01-13 12:02:20 -08:00
Ryan Houdek e884525434 Fixes 16bit addr offset calculation 
In the case of 16bit addressing mode, the upper bits 16bits are zext
prior to result.

Ryan Houdek 1084ecf2d3 Fixes more 16bit modrm addressing problems 
In the case of an instruction that used 16bit addressing mode. It would
calculate the amount of displacement needing to be read using a 32bit
modrm mode. It would then read calculate modrm displacement again and
read the correct number of bytes.

Leftover bytes would then be in a mismatched state which means if an
instruction was using 16bit addressing + modrm + literal at /that/ point
the number of literal bytes remaining would be calculated as a negative.

This didn't actually break things since instructions that have modrm +
literal and can safely use 16bit addressing without breaking in a 32bit
environment is impossible on Linux. Due to the inability to map a memory
range in 16bit range.

Disables killpg tests and reenables a few tests
 2021-01-11 19:32:35 +02:00
Ryan Houdek b857d6ba16 Disables killpg tests and reenables a few tests 
killpg has been causing us testing problems for a while now.
As we were running more tests it was becoming more likely to hit a test
doing killpg in the background.

All of the tests run under the same process group so it is a significant
race condition to have these running.
Until we improve CI to somehow work around how killpg works, we just
need to have these disabled.

Ryan Houdek 43af4e26d1 Fixes 64bit ELF loading when LLVM ASAN is used 
Instead of hardcoding 64bit dynamic ELF files to 0x1'0000'0000 we
instead calculate the size of the ELF in memory. Then allocate the
ELF base up front.

LLVM ASAN steals a large amount of virtual memory space that intersected
with the original hardcoded range which caused memory allocations to
fail.

Ryan Houdek aa3b77e4c8 Uninstalls LogManager handlers on shutdown

message, this will no longer crash.

Ryan Houdek f83698cb50 Uninstalls SignalDelegator signals on destruction 
Tear this down earlier so if we catch a signal on shutdown then we don't
crash in the handler.
