We've got a switch to disable v7m code since a long time - but it
currently cannot be disabled since linking then fails due to missing
functions. But thanks to the clean-ups that have been done during the
past years, it's not that difficult anymore to finally make it possible
to disable CONFIG_ARM_V7M: We just have to move some v7m-related code
out of cpu32.c to a separate file (that we only compile if the switch
CONFIG_ARM_V7M is enabled) and make sure to use the stub functions in
m_helper.c if it is disabled. Then we can finally remove the hard-coded
"select ARM_V7M" from the Kconfig file.
v3:
- Rebase to current master branch
- Make sure that the stubs use g_assert_not_reached() in the second patch
v2:
- Updated a comment
- Avoid #ifdef in cpu-v7m.c, handle it via meson.build instead
Thomas Huth (3):
target/arm: Move v7m-related code from cpu32.c into a separate file
target/arm/tcg/m_helper.c: Include the full helpers only with
CONFIG_ARM_V7M
target/arm/Kconfig: Stop requiring CONFIG_ARM_V7M
