Optimizer "b" issue

[githubaf]

While working on testing of WCS I encountered another issue

When compiled with -O0 for 68020 WCS renders correctly. With -O2 the sun and moon become black.
The problem occurs in GlobeMapSupport.c in function Celestial_Bodies().

I experimented with -fbbb settings and the problem disappears if I remove the "b" option.

Please find attached the preprocessed source.

My compiler command line is
m68k-amigaos-gcc -DFORCE_MUIMASTER_VMIN=19 -DSTATIC_FCN= -DAMIGA_GUI -DTOOLCHAIN_VER=\"'%@@=492:?iaf}@Gac 9EEADi^^8:E9F3]4@>^3633@^2>:82\\844]8:E $sxic2f7d7e 2>:82\\844i__ffc7_ 2>:82\\?6E:?4=F56id2bhe2a 2C@D\\DEF77i4_2_e3c 3:?FE:=Dih32_3b32 4=:3ai6223dd 75aAC28>2i6hg7_h_ 75aD75i35f6e55 844i3de54dae :C2i333f2ge :I6>F=i7_55hhf =:3$s{aibac7e34 =:3563F8ica5h5b2 =:3?:Iibebca44 ?6H=:3\\4J8H:?i3b56bh4 D754i_6h72ag G2D>i5a73hb G344idae6h2_ G=:?<ih3b5be'\" -I"/home/developer/Desktop/SelcoGit/3DNature/Amiga" -O2 -Wall -c -fmessage-length=0 -funsigned-char -MMD -MP -MF"GlobeMapSupport.d" -MT"GlobeMapSupport.o" -o "GlobeMapSupport.o" "../GlobeMapSupport.c" -DBUILDID=\"g/'18b45a4-dirty'\" -noixemul -m68020 -m68881 -DSTATIC_FCN= -DSTATIC_VAR=static -Winline -DSWMEM_FAST_INLINE

The problem also occurs when compiled with -m68040 -m68881.
It does not occure when compiled with -m68060 -m68881 or -m68020-60 -m68881

the insns contain something new (for me):

(fix:DF (mem:DF (plus:SI (reg:SI 11 a3)
                    (const_int 456 [0x1c8])) [0  S8 A16])))

the fix:DF is not handled correctly

please test

can't reproduce, sorry

[bebbo]

btw: Ubuntu 22.04.5 LTS should create some crash report.

Thanks for looking.
I see the same problem on another PC running Ubuntu 20.04 Focal Fossa.
I will try to find more info...

Merry Christmas!

Happy new year!

The issue (gcc internal compiler error) started with the commits from 12.Dec.
Last working version was from 8.Dec.

The commit from yesterday, 8.Jan

projects/gcc
commit f4faa83
refs #241: prevent infinite loop

has solved the issue! GCC works again. Also the black sun and moon are fixed.
Thank you!

[bebbo]

Happy new year too!

Thanks for the reporting and your patience :-)
