From: Alessandro Di Federico <a...@rev.ng> This patchset introduces the idef-parser for target/hexagon.
It's the third iteration of the patchset and includes fixes suggested in the previous iteration. `idef-parser` is a build-time tool built using flex and bison. Its aim is to generate a large part of the tiny code generator frontend for Hexagon. The prototype of idef-parser has been presented at KVM Forum 2019 ("QEMU-Hexagon: Automatic Translation of the ISA Manual Pseudcode to Tiny Code Instructions"): https://www.youtube.com/watch?v=3EpnTYBOXCI `target/hexagon/idef-parser/README.rst` provides an overview of the parser and its inner working. A couple of notes: * `idef-parser` also supports certain things that are not used in the most recently submitted version of the "Hexagon patch series". However, they will be needed and stripping them out of the parser is quite a bit of work. * checkpatch.pl complains on a single macro which has a trailing semi-colon, which is required. * The build on the CI fails for the cross-i386-* jobs. This seems to be due to the fact that, despite we specified glib as a native dependency, meson still chooses the i386 bit version of the library, as opposed to the x86-64. * This implementation no longer employs a conditional move to implement the ternary operator of the input language. We now employ proper control flow instructions (brcond). This is due to the fact that certain ternary expression have side effects. As a side effect, we had to switch from temporaries to local temporaries.
