1273 \`configure' configures RISC-V ISA Simulator ? to adapt to many kinds of systems.
1274
1275 Usage: $0 [OPTION]... [VAR=VALUE]...
1276
1277 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1278 VAR=VALUE.  See below for descriptions of some of the useful variables.
1279
1280 Defaults for the options are specified in brackets.
1281
1282 Configuration:
1283   -h, --help              display this help and exit
1284       --help=short        display options specific to this package
1285       --help=recursive    display the short help of all the included packages
1286   -V, --version           display version information and exit
1287   -q, --quiet, --silent   do not print \`checking ...' messages
1288       --cache-file=FILE   cache test results in FILE [disabled]
1289   -C, --config-cache      alias for \`--cache-file=config.cache'
1290   -n, --no-create         do not create output files
1291       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1292
1293 Installation directories:
1294   --prefix=PREFIX         install architecture-independent files in PREFIX
1295                           [$ac_default_prefix]
1296   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1297                           [PREFIX]
1298
1299 By default, \`make install' will install all the files in
1300 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1301 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1302 for instance \`--prefix=\$HOME'.
1303
1304 For better control, use the options below.

1349                           Enable all optional subprojects
1350   --enable-commitlog      Enable commit log generation
1351   --enable-histogram      Enable PC histogram generation
1352   --enable-dirty          Enable hardware management of PTE accessed and dirty

1354
1355 Optional Packages:
1356   --with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
1357   --without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
1358   --with-isa=RV64IMAFDC   Sets the default RISC-V ISA
1359   --with-fesvr            path to your fesvr installation if not in a standard
1360                           location
1361
1362 Some influential environment variables:
1363   CC          C compiler command
1364   CFLAGS      C compiler flags
1365   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1366               nonstandard directory <lib dir>
1367   LIBS        libraries to pass to the linker, e.g. -l<library>
1368   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1369               you have headers in a nonstandard directory <include dir>
1370   CXX         C++ compiler command
1371   CXXFLAGS    C++ compiler flags
1372   CXXCPP      C++ preprocessor
1373   STOW_ROOT   Root for non-native stow-based installs
1374   STOW_PREFIX Prefix for stow-based installs
1375
1376 Use these variables to override the choices made by `configure' or to help
1377 it to find libraries and programs with nonstandard names/locations.
