Subject: Follow-up to previous commit about forcing thumb builds:
X-Git-Tag: upstream/5.2.1~669^2~76
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=10be273b3c804d86ee6dde5f550fd76217a8a77d;p=platform%2Fupstream%2Fqtdeclarative.git

Follow-up to previous commit about forcing thumb builds:

Disable the checks of the thumb bit in code pointers when building for Android,
because we want to allow for intermixing of thumb (what the JIT generates) and
arm code (what the compiler generates for run-time functions we call, in debug
builds)
