Bootloader fork rebase:
- Base changed from 0.1.0 pre-patched archive to upstream 1.0.0 tag (c7eeb9f)
- Applied 0001-redbear-local-forks.patch (Cargo.toml crate path redirects)
- Applied fix-uefi-alloc-panic.patch equivalents (4 panic!() -> graceful
error handling in src/main.rs)
- Applied P5-live-preload-cap-1gib.patch (1 GiB cap on live image preload)
- Skipped: P0 GPT partition scan (requires new module + integration),
P1 timeout/default-resolution, P2 live preload guard (subsumed by
panic fixes + cap), P3 live image safe read, P4 large ISO boot,
redox.patch — to be applied in dedicated rebase session.
firmware-loader/Cargo.toml: version 0.1.0 -> 0.3.0 (sync with other
Red Bear custom crates which are at 0.3.0).
fork-upstream-map.toml: bootloader back from PENDING_REBASE to 1.0.0
since the partial rebase matches upstream 1.0.0 content.
fork-upstream-map.toml: base restored to 'main' tracked (was correctly
tracked by build-redbear.sh).

# gl_WARN_ON_USE_PREPARE(INCLUDES, NAMES)
|
|
# ---------------------------------------
|
|
# If the module 'posixcheck' is in use:
|
|
#
|
|
# For each whitespace-separated element in the list of NAMES, define
|
|
# HAVE_RAW_DECL_name if the function has a declaration among INCLUDES
|
|
# even after being undefined as a macro.
|
|
#
|
|
# See warn-on-use.h for some hints on how to poison function names, as
|
|
# well as ideas on poisoning global variables and macros. NAMES may
|
|
# include global variables, but remember that only functions work with
|
|
# _GL_WARN_ON_USE. Typically, INCLUDES only needs to list a single
|
|
# header, but if the replacement header pulls in other headers because
|
|
# some systems declare functions in the wrong header, then INCLUDES
|
|
# should do likewise.
|
|
#
|
|
# It is generally safe to assume declarations for functions declared
|
|
# in the intersection of C89 and C11 (such as printf) without
|
|
# needing gl_WARN_ON_USE_PREPARE.
