83 l1_sync_intram.obj: ditto 83
84 The last function in this module is l1s_dedicated_mode_manager();
85 the two preceding functions match perfectly, but for this last function
86 when the reconstructed code is recompiled, the compiler's register
87 allocator makes different picks for reasons that could not be
88 successfully reversed. Because the code is compiled in Thumb mode
89 and the compiler made a different choice between low and high registers
90 in some places, the instructions do not line perfectly. The logic match
91 has instead been verified by manual comparison.
92
93 l1_sync_intram.obj:
94
95 Similar situation in the l1s_schedule_tasks() function: the function
96 is huge, there is an unknown set of factors determining what the
97 compiler's register allocator will do, and in this case there is even
98 a difference in the choice of register vs. stack for some temporaries.
99 As a result, the code does not line up and the logic had to be verified
100 manually. All other functions (preceding and following) match
101 perfectly.
