In:
lldb\source\Plugins\Process\Windows\Common\CMakeLists.txt
these files are built based on the SYSTEM Architecture:
if(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64|AMD64")
target_sources(lldbPluginProcessWindowsCommon PRIVATE
x64/RegisterContextWindows_x64.cpp)
elseif(CMAKE_SYSTEM_PROCESSOR MATCHES "i?86|X86")
target_sources(lldbPluginProcessWindowsCommon PRIVATE
x86/RegisterContextWindows_x86.cpp)
endif()
but later they're used based on the defines (which will the target arch, it's
not uncommon to compile on x86_64 for i386, since the engine has to match
exactly on Windows)
#if defined(_M_AMD64)
...
#if defined(_M_IX86)
...
Locally I've changed this to unconditionally include the files and use ifdefs
in the context files. but that is less than ideal.
