…a-xyz#4) * [BPF] Make rust allocation builtins unavailable for BPF target - the calls to rust alloc/dealloc routines need to be preserved and not replaced by compiler generated builtin inlined code
* [SOL][BPF] Adjust BPF tests * [SOL][BPF] Improve reporting of stack size is too large - issue only one warning for each function - report the function location if debug information is available

* [SOL] Make lld thread-safe with llvm when used in-process Every time Solang tries to link a web-assembly file in-process, the linker re-inits llvm which is not thread-safe with the rest of solang. Signed-off-by: Sean Young <[email protected]> * [SOL][BPF] Enable the _ExtInt extension on the BPF Target for Solana Signed-off-by: Sean Young <[email protected]>
Solana extends BPF so that structs type information is not fully supported in BTF. This leads to ICE crashes and some unsupported relocations being emitted in binary files that linker errors on. For, now the debug information is simply disabled when compiling for Solana to avoid the errors in Debug builds.
Because of a bug in BPF backend ABS64 relocations are incorrectly generated as 64_64 relocations in BPF object files. This temporary works around this for relocations in .debug section to generate debug information addresses correctly.
This change rust-lang@ab4fc87 breaks compilation of compiler-rt library for BPF and SBF targets. For now disabling it.
These tests currently fail on some Macs for some versions of Python, causing our CI to fail. See, e.g., llvm#62403 and references therein.
This PR replaces sub r11, imm by add r11, -imm and is the equivalent of solana-labs/rbpf#488 for the SBF target in LLVM. This is the first task in solana-labs/solana#34250
Patch anza-xyz#54 originally reworked the SBF textual assembly syntax to match the rbpf-style syntax. In order to allow some soak-time, the above patch temporarily supported both the old and new syntax (selectable on the command line or via bespoke assembler directives). A little over a year has passed since then, and all is well with the new syntax, testing, and so forth. The current patch now removes all existing remnants of the old syntax-- including some of the target-independent changes made in the original patch to support both (e.g., a minor TableGen change for variants, some additional command line selector flags, etc). All related unit tests have been updated accordingly.
Following the alterations made in solana-labs/rbpf#489, this PR removes the neg instructions and changes the semantics of sub when one of the operands is an immediate. sub r1, 2 now means r1 = 2 - r1, instead of r1 = r1 - 2. neg r1 is represented as r1 = 0 - r1. This is the second task in solana-labs/solana#34250.
This PR addressed two more items in solana-labs/solana#34250. It removes the little endian byte swap instructions (solana-labs/rbpf#493) and the input buffers related instructions (solana-labs/rbpf#251).
