Summary MacroAssemblerARMv7::branch32 may clobber its own arguments
Max Rottenkolber
Reported 2025-02-20 04:30:59 PST
On armv7 certain uses of branchPtr cause it to clobber its own arguments, leading to bogus assembly. We need to catch this pitfall at least in debug builds and fix instances of this bug.
