• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Carlos Alberto Lopez Perez]

MIPS32 Build its failing to build since r260246 with this error:

FAILED: [...] Source/JavaScriptCore/CMakeFiles/LowLevelInterpreterLib.dir/llint/LowLevelInterpreter.cpp.o -c ../../Source/JavaScriptCore/llint/LowLevelInterpreter.cpp

This has been bisected in the bot:
ordered build on r260245: worked (I stopped it on the test phase) -> https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4844
ordered build on r260246: failed -> https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4845

And to discard it was not an iterative build issue I also tested with clean builds:
clean ordered build on r260245: worked (the build phase) -> https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4847
clean ordered build on r260246: failed -> https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4846
