Update WPEWebKit to the 2.52 stable major release branch. Includes a pending patchset to get WASM BBQJIT working on RISCV64, upstream PR https://github.com/WebKit/WebKit/pull/65621 Alltogether this brings acceptable performance (even with LLVMPipe Mesa software renderer) on RISCV64.

Subject: [PATCH] JavaScriptCore: emit the RISCV64 LLInt arch attribute only once
|
|
|
|
The RISCV64 variant of OFFLINE_ASM_GLOBAL_LABEL_IMPL emits a
|
|
'.attribute arch, "rv64gc"' directive for every global label in the
|
|
generated LLInt assembly. The whole LLInt is emitted as a single
|
|
top-level __asm__ block, so from the second label onwards the
|
|
directive appears after instructions have already been emitted, and
|
|
recent binutils rejects it:
|
|
|
|
{standard input}: Fatal error: architecture elf attributes must
|
|
set before any instructions
|
|
|
|
The ELF architecture attribute is already emitted once for the
|
|
translation unit by the compiler from -march=rv64gc, which equally
|
|
covers the rv64gc instructions in the LLInt asm. Drop the RISCV64
|
|
special case so the generic OFFLINE_ASM_GLOBAL_LABEL_IMPL is used,
|
|
which does not emit the redundant per-label directive.
