Bug 266218 – [GTK] webkitgtk 2.43.2 fails to build on riscv64 JavaScriptCore/offlineasm/riscv64.rb

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Jeremy Bicha]

webkitgtk 2.43.2 (and 2.43.1) fails to build on Debian and Ubuntu's riscv64 but seems to build ok on other architectures.


/Source/JavaScriptCore/offlineasm/riscv64.rb:132:in `riscv64RaiseMismatchedOperands':
 Unable to match operands [RegisterID, RegisterID, LabelReference] (due to LowLevelInterpreter64.asm:258) (LoweringError)

In an attempt to work around this issue since I eventually need webkitgtk 2.43 to build on Ubuntu's riscv64, I did a build with
-DENABLE_JIT=OFF -DENABLE_C_LOOP=ON -DENABLE_WEBASSEMBLY=OFF

This also caused the build to fail:

This is still broken, so we decided to work around this downstream in Debian by using WTF_CPU_UNKNOWN in riscv64.
