Improve build system
- Reduce full build latency from ~20s to ~18s - Bring back silent mode if `make V=0` is passed - Demodernize utimes() polyfill so it works RHEL5 - Delete some old shell scripts that are no longer needed - Truncate long lines when outputting builds to Emacs buffers

# HELLO BUILD

#
|

# OVERVIEW

#
|

# We generate a line at the start of each Makefile run, because if we

# use `make V=0` mode then the terminal logging trick we use in
|
||||
# tool/build/compile.c will delete the previous line, and we'd rather
|
||||
# have that line not be the bash prompt that ran make.
|
||||
#
|
||||
# This script is also useful for giving us an indicator each time the
|
||||
# build restarts itself from scratch, which can happen in cases like
|

# when dependencies need to be regenerated by tool/build/mkdeps.c

Compiler Collection Frontend Frontend\n\

\n\
|
||||
DESCRIPTION\n\
|
||||
\n\
|
||||
This launches gcc or clang after scrubbing flags.\n\
|
||||
This is a generic command wrapper, e.g.\n\
|
||||
\n\
|
||||
EXAMPLE\n\
|
||||
compile.com gcc -o program program.c\n\
|
||||
\n\
|
||||
compile.com gcc -o program program.c\n\
|
||||
This wrapper provides the following services:\n\
|
||||
\n\
|
||||
- Ensures the output directory exists\n\
|
||||
- Echo the launched subcommand (silent mode supported if V=0)\n\
|
||||
- Magic filtering of GCC vs. Clang flag incompatibilities\n\
|
||||
- Unzips the vendored GCC toolchain if it hasn't happened yet\n\
|
||||
- Making temporary copies of APE executables w/o side-effects\n\
|
||||
- Truncating long lines in \"TERM=dumb\" terminals like emacs\n\
|
||||
\n\
|
||||
This wrapper is extremely fast.\n\
|
||||
\n\
|
||||
FLAGS\n\
|
||||
\n\
|
||||
-A ACTION specifies short command name for V=0 logging\n\
|
||||
-T TARGET specifies target name for V=0 logging\n\
|
||||
-t touch target on success\n\
|
||||
-n do nothing (used to prime the executable)\n\
|
||||
-? print help\n\
|
||||
\n"
