/*
 * Linker script for tools/flibc_demo_elf.zig — same single-PT_LOAD
 * shape as tools/hello_linker.ld, extended to capture `.rodata*` (printf
 * format strings, the "flibc malloc ok" message) and any `.data*` /
 * `.bss*` the compiler may emit. flibc's bump allocator stores no state
 * (each malloc is a thin sbrk wrapper, returning the previous break),
 * so a writable PT_LOAD is unnecessary; folding rodata/data/bss into
 * the R+X LOAD keeps the blob at one segment, which in turn keeps it
 * inside sys_exec's PAGE_SIZE snapshot cap.
 *
 * Layout:
 *   . = 0         — start of the only LOAD segment, page-aligned.
 *   .text         — code (entry point _start lives here).
 *   .rodata*      — printf format spec literals etc.
 *   .data*        — comptime-emitted constants (expected zero-sized).
 *   .bss*         — zero-initialized data (expected zero-sized; if
 *                   non-zero the demo would store-fault on first write
 *                   because the LOAD is R+X — clear runtime signal that
 *                   the state-free bump-allocator invariant has been
 *                   broken).
 *
 * eh_frame/note/comment/dyn* sections are discarded — the demo is small
 * enough that none of its Zig codepaths emit unwind tables, and the
 * stock LLD layout would otherwise split .eh_frame_hdr / .eh_frame into
 * a leading R-only LOAD that bumps .text past the page-aligned base
 * the FlashOS loader requires.
