| * | Change single cycle core with delay slot to use separate fetch stage. | Pavel Pisa | 2019-03-26 |
| | | | | | | | | | | | | | When instructions are visualized then it is even more misleading to keep old instruction in decode phase delay buffer. The single cycle core with delay slot is upgraded to the variant with fetch and execute phases. This way the structure is logical and delay slot has purpose.

| | | | | | | | | | | | | | | | | | library changes. I have not found a way how to pass additional CONFIG options to Debian package build (dpkg-buildpackage) when qmake is invoked from debian/rules with debian helper based (dh) build. The way how qmake solves dependencies between program and libraries comes from stone age. It is necessary to include complete path to the library in PRE_TARGETDEPS definition including lib prefix and .a suffix. This is non portable and cannot be easily used when static and dynamic libraries build alternatives are considered. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> | ||
