#2987 gcc-torture-execute-strlen-4.c fails

[Philipp Klaus Krause]

Now that gcc-torture-execute-strlen-4.c compiles, the test still fails when enabled.
We need to check if that is okay (maybe it just relies on GCC implementation-defined behaviour with SDCC making different choices) or a real SDCC bug.

[Philipp Klaus Krause]

Looking further into this, it looks like real SDCC bugs.

• For all ports it fails in test_ptr_array.
• For stm8, it failed in test_array_ptr due to a bug in handling signed char literals; I fixed it in [r11559].
• For hc08 and s08 it fails for some other reason in test_array_ptr.

[Philipp Klaus Krause]

I can still reproduce this issue on my Debian GNU/Linux testing system as of [r13824].

[Gabriele Gorla]

I root caused the bug in incorrect handling of a signed byte in the hc08 codegen that was also copied to the mos6502 ports.

[Gabriele Gorla]

[r14561] fixes the issue for both mos6502 and hc08

If you replace the tabs with spaces as it should be it would look well in every view / editor.
Have a look at the commit link [r14561] to see how it currently fails.

[Gabriele Gorla]

You're right.
I need to be more careful with the editor settings.
