* tcg: Remove TCG_CT_REGRichard Henderson2020-10-081-2/+0Star
| | | | | | | | This wasn't actually used for anything, really. All variable operands must accept registers, and which are indicated by the set in TCGArgConstraint.regs. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* tcg: Drop union from TCGArgConstraintRichard Henderson2020-10-081-7/+7
| | | | | | | | The union is unused; let "regs" appear in the main structure without the "u.regs" wrapping. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* meson: rename included C source files to .c.incPaolo Bonzini2020-08-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* tcg/riscv: Fix RISC-VH host build failureAlistair Francis2019-07-091-2/+2
| | | | | | | | | | | | | Commit 269bd5d8 "cpu: Move the softmmu tlb to CPUNegativeOffsetState' broke the RISC-V host build as there are two variables that are used but not defined.

| | | | | | | | | | | We have for some time had code within the tcg backends to handle large positive offsets from env. This move makes sure that need not happen.
