| Message-ID | <[email protected]> |
With this implementation, you can build ELF file and execute it on
baremetal esp32/esp32s3 chip or QEMU simulation.
Build your app easily with provided GCC spec files.
See more details here:

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+//
+// GENERAL NOTES:
+//
+// These window exception handlers need not be modified.
+// They are specific to the windowed call ABI only.
+//
+// Underflow Handlers:
+//
+// The underflow handler for returning from call[i+1] to call[i]
+// must preserve all the registers from call[i+1]'s window.
+// In particular, a0 and a1 must be preserved because the RETW instruction
+// will be reexecuted (and may even underflow again if an intervening
+// exception has flushed call[i]'s registers).
+// Registers a2 and up may contain return values.
+//
+// The caller could also potentially assume that the callee's a0 and a1
+// (its own a4&a5 if call4, a8&a9 if call8, a12&a13 if call12)
+// are correct for whatever reason (not a clean thing to do in general,
+// but if it's possible, unless the ABI explicitly prohibits it,
+// it will eventually be done :) -- whether the the ABI needs to
+// prohibit this is a different question).
+//
+// Timing of Handlers:
+//
+// Here is an overview of the overhead of taking a window exception,
+// ie. the number of additional cycles taken relative to case where
+// an exception is not taken.
+// NOTE: these numbers do not take into account any cache misses,
+// write buffer stalls, or other external stalls, if they occur.
+// The totals consist of 5 cycles to enter the handler (or 6 or 7
+// for optional longer pipelines in Xtensa LX), the number of instructions
+// and interlocks (2nd and 3rd columns below), and 2 cycles jump delay
+// on return (3 cycles for optional longer I-side pipeline in Xtensa LX):
