Because of misplaced `From` value, comment we not adopted by
the recompilable archive, leading to desyncronization between it
and the usual decompilation branch of the pipeline.
The `namespace` property is strictly used just by the cpp generator.
Move the code so the `--namespace` option is exclusive to it and removed
for all the other generators.
Merge all the command-line scripts for generating tuple-tree
implementations into a single `tuple-tree-generate.py` script. Move all
the other files a directory down.
This commit turns on some old tests that were disabled for a bug.
The comment on the disabled tests said that it was due to a bug in type
inlining, but it was actually caused by a bug in the computation of
dependencies in DepenencyGraph.
Type inlining is now gone, and DependencyGraph has been fixed, so it's
now possible to re-enable these tests.
Type inlining was a feature that allowed type definitions of
structs/unions/enums to be printed in C directly inside the definition
of another parent struct/union, if the inner type was only used once in
the parent type.
This kind of reasoning is inherently global: a type definition of the
subtype can be inlined in the parent type one only if *globally* the
subtype it isn't referred anywhere else.
This caused issues with type inlining inside definitions of stack types
in the body of functions. Indeed, for a given function, due to type
inlining, it was necessary to do global reasoning about what other types
could be inlined in the definition of the function's stack frame type.
This, in turn, had heavy consequences on invalidation, because any
change to any type (even if it wasn't referred in a given function's
body) was causing invalidation of all functions' bodies.
For this reason it was decided to drop the type inlining feature.
Add a python interface (`revng.profile`) for interacting with the rev.ng
infrastructure as a whole; either through the CLI (`CLIProject`) or the
GraphQL API (`DaemonProject`).
The logic of the `revng ptml` command was too tightly coupled with the
parsing of the xml. Overhaul the structure of the ptml code and split it
in two locations:
* `revng.ptml`: this module contains functions that allow easy
manipulation of PTML, both for printing it and for obtaining the split
metadata/text version.
* `revng.internal.cli._commands.ptml`: this implements the actual `revng
ptml` command. This leverages the new logic in the `revng.ptml` module
while maintaining the same functionality.
In this commit we instruct the build system to use the unified schema
files instead of collecting the `TUPLE-TREE-YAML` comments.
The fixes to C++ files are necessary because they depend on the order
of the fields in the schema, which was changed.
This pass wraps LLVM's vanilla InstCombine, to hijack one of its
options. The goal of this hijack is to prevent InstCombine from
splitting and replacing accesses to arrays with GEPs and smaller
accesses.
This pass wraps LLVM's vanilla SROA, to hijack one of its options.
The goal of this hijack is to prevent SROA from splitting and replacing
memory accesses to arrays with GEPs and smaller accesses.
