First runtime bring-up on Linux (Ubuntu, gcc-14). -level_09 now renders
past frame 1200 crash-free with a clean shutdown, matching Windows.
- port/src/romdata.c: no-PIE loads the image at 0x400000, so the D34
'clear low 32 bits of a symbol address' gives 0 -> false 'image base not
4GiB-aligned' abort. The ANIM_DATA_* lvalues are only ever address-taken
(never dereferenced), so fall back to a fixed 4GiB-aligned sentinel
(0x100000000) for g_pc_animdata_base.
- port/src/main.c: the 'image must load at 0x140000000' assertion is
PE-specific (.refptr base relocations); ELF no-PIE resolves dram_syms.s
absolute symbols literally regardless of load address. Guard it to
PLATFORM_WINDOWS.
- port/src/libultra.c: mmap game-thread stacks with MAP_32BIT so they sit
in the low 2GiB. The decomp truncates stack-buffer pointers to u32 (e.g.
in texLoad); glibc pthread stacks live above 4GiB and
those truncations corrupt. One fix covers the whole idiom class. Windows
pthread stacks are already low.
- src/game/image.c: belt-and-braces #ifdef PORT -- align compbuffer at
uintptr_t width (identical result on N64).
- CMakeLists.txt: drop the -Ttext-segment experiment (needs -mcmodel=large;
breaks R_X86_64_32 relocs) -- comment only.
Windows: build 240/241, -level_09 crash-free past frame 1440.
