2019-07-04target/arm/helper: Move M profile routines to m_helper.cPhilippe Mathieu-Daudé
In preparation for supporting TCG disablement on ARM, we move most of TCG related v7m/v8m helpers and APIs into their own file. Note: It is easier to review this commit using the 'histogram' diff algorithm: $ git diff --diff-algorithm=histogram ... or $ git diff --histogram ...

2019-07-04target/arm: Restrict semi-hosting to TCGPhilippe Mathieu-Daudé
Per Peter Maydell: Semihosting hooks either SVC or HLT instructions, and inside KVM both of those go to EL1, ie to the guest, and can't be trapped to KVM. Let check_for_semihosting() return False when not running on TCG.

2019-06-13target/arm: Add stubs for AArch32 VFP decodetreePeter Maydell
Add the infrastructure for building and invoking a decodetree decoder for the AArch32 VFP encodings. At the moment the new decoder covers nothing, so we always fall back to the existing hand-written decode. We need to have one decoder for the unconditional insns and one for the conditional insns, as otherwise the patterns for conditional insns would incorrectly match against the unconditional ones too. Since translate.c is over 14,000 lines long and we're going to be touching pretty much every line of the VFP code as part of the decodetree conversion, we create a new translate-vfp.inc.c to hold the code which deals with VFP in the new scheme. It should be possible to convert this into a standalone translation unit eventually, but the conversion process will be much simpler if we simply #include it midway through translate.c to start with.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
