# Vendored third-party: zlib + minizip-ng (ZIP, C) and unrar 7.20.1 (RAR,

# main()); the project talks to it through the extern "C" DLL API in
# third_party/unrar7/unrar_c_api.h. Compiled with relaxed warnings (-w) —
# these are not our code and we do not want to chase upstream style updates.
#
# C++ compilers: PS5 uses prospero-clang++ (FreeBSD-style sysroot; the
# toolchain defaults to -stdlib=libc++, driver links libc++ automatically);
# host builds use the plain host C++ compiler (libstdc++).

# Assembly-optimised LZMA decoder (optional, on when jwasm is present).
#
# LzmaDec.c carries a compile-time switch: with Z7_LZMA_DEC_OPT it calls an
# external LzmaDec_DecodeReal_3() and drops its own C implementation; without
# it, the C version is used. The asm version is measurably faster -- on a
# 330 MiB LZMA2 archive, 1.10 s vs 1.39 s, i.e. most of the gap to the
# official 7-Zip binary, which builds with this switch on.
#
# LzmaDecOpt.asm is MASM syntax, so it needs a MASM-compatible assembler
# (jwasm). That is not something we can assume the host has, so the whole
# optimisation is conditional: no jwasm, no asm, and the build still works.
# ABI_LINUX is load-bearing -- 7zAsm.asm keys its calling convention off it
# (SysV rdi/rsi/rdx vs Win64 rcx/rdx/r8); assembling without it links cleanly
# and then segfaults on the first call.
