> Subject: [PATCH] driver: Support very long command lines via temporary files
> [PR111527]
>
> From: Sunil Dora <[email protected]>
>
> This patch allows the driver to handle very long command lines by
> writing COLLECT_GCC_OPTIONS content to a temporary file when it
> exceeds system limits (typically 128K).
>
> The environment variable is then set to reference this file
> using '@' syntax, and subprocesses (collect2, lto-wrapper,
> lto-plugin) are updated to read from such files.
>
> gcc/ChangeLog:
> * gcc.cc (set_collect_gcc_options): Write COLLECT_GCC_OPTIONS to a
> temporary file.
> * collect2.cc (main): Use getenv_extended for COLLECT_GCC_OPTIONS.
> * lto-wrapper.cc (run_gcc): Use getenv_extended for
> COLLECT_GCC_OPTIONS.
>
> gcc/testsuite/ChangeLog:
> * gcc.dg/longcmd/longcmd.exp: New test suite.
> * gcc.dg/longcmd/pr111527-1.c: New test.
> * gcc.dg/longcmd/pr111527-2.c: New test.
> * gcc.dg/longcmd/pr111527-3.c: New test.
> * gcc.dg/longcmd/pr111527-4.c: New test.
>
> libiberty/ChangeLog:
> * Makefile.in: Add env-extended.c to build.
> * env-extended.c: Add implementation of getenv_extended.
> * include/libiberty.h (getenv_extended): New declaration.
>
> lto-plugin/ChangeLog:
> * lto-plugin.c (onload): Use getenv_extended for COLLECT_GCC_OPTIONS.
