Subject: [PATCH 006/120] MIPS: R5900: Workaround for the short loop bug
Date: Sun, 1 Sep 2019 17:38:44 +0200
Message-ID: <d59a6bef6541d35d4460b966c0fe651aac507730.1567326213.git.noring@nocrew.org> (raw)
In-Reply-To: <cover.1567326213.git.noring@nocrew.org>

The short loop bug under certain conditions causes loops to execute
only once or twice. The Gnu assembler (GAS) has the following note
about it:

    On the R5900 short loops need to be fixed by inserting a NOP in the
    branch delay slot.

    The short loop bug under certain conditions causes loops to execute
    only once or twice. We must ensure that the assembler never
    generates loops that satisfy all of the following conditions:

    - a loop consists of less than or equal to six instructions
      (including the branch delay slot);
    - a loop contains only one conditional branch instruction at the
      end of the loop;
    - a loop does not contain any other branch or jump instructions;
    - a branch delay slot of the loop is not NOP (EE 2.9 or later).

    We need to do this because of a hardware bug in the R5900 chip.

GAS handles the short loop bug in most cases. However, GAS is unable
to adjust machine code having the noreorder directive, as used by the
kernel on several occasions.

The short loop bug also affects user space code, which is why generic
MIPS code cannot execute unadjusted on the R5900. The GAS and GCC option
-mfix-r5900 is recommended for such cases.
