For example, there are 11 registers labeled `"x2`. It should be printed as follows: ``` -- Machine register context ------------------------------------------------ x0: 0x0000000000000000 x1: 0x000000000000000b x2: 0x0000000000000000 x3: 0x5345475600000000 x4: 0x0000000000000000 x5: 0x5345475600000000 x6: 0x000000000108e600 x7: 0x000000000000f00f x18: 0x0000000000000000 x19: 0x000000000000000b x20: 0x0000005501286080 x21: 0x0000000000003284 x22: 0x0000000000000002 x23: 0x0000000000000001 x24: 0x0000000000000001 x25: 0x0000000000000001 x26: 0x0000005500b85264 x27: 0x0000005500b8518c x28: 0x0000000000080b90 x29: 0x00000055007fea30 sp: 0x00000055007fe970 fau: 0x0000000000000000 ``` The same goes for ARM Linux. ---Files-------------------------------- ruby-vm_dump-arm-regstr.patch (3.37 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
