| | | | | | | | | | | This bit is not saved across interrupts, so we must delay delivering the interrupt until the skip has been processed.

* meson: targetPaolo Bonzini2020-08-211-1/+1
| | | | | | | | | Similar to hw_arch, each architecture defines two sourceset which are placed in dictionaries target_arch and target_softmmu_arch.

* meson: rename included C source files to .c.incPaolo Bonzini2020-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | With Makefiles that have automatically generated dependencies, you generated includes are set as dependencies of the Makefile, so that they are built before everything else and they are available when first building the .c files. Alternatively you can use a fine-grained dependency, e.g. target/arm/translate.o: target/arm/decode-neon-shared.inc.c With Meson you have only one choice and it is a third option, namely "build at the beginning of the corresponding target"; the way you express it is to list the includes in the sources of that target. The problem is that Meson decides if something is a source vs. a generated include by looking at the extension: '.c', '.cc', '.m', '.C' are sources, while everything else is considered an include---including '.inc.c'. Use '.c.inc' to avoid this, as it is consistent with our other convention of using '.rst.inc' for included reStructuredText files. The editorconfig file is adjusted.
