|
# AX_C_FLOAT_WORDS_BIGENDIAN([ACTION-IF-TRUE], [ACTION-IF-FALSE], [ACTION-IF-UNKNOWN])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Checks the ordering of words within a multi-word float. This check is
|
|
# necessary because on some systems (e.g. certain ARM systems), the float
|
|
# word ordering can be different from the byte ordering. In a multi-word
|
|
# float context, "big-endian" implies that the word containing the sign
|
|
# bit is found in the memory location with the lowest address. This
|
|
# implementation was inspired by the AC_C_BIGENDIAN macro in autoconf.
|
|
#
|
|
# The endianness is detected by first compiling C code that contains a
|
|
# special double float value, then grepping the resulting object file for
|
|
# certain strings of ASCII values. The double is specially crafted to have
|
|
# a binary representation that corresponds with a simple string. In this
|
|
# implementation, the string "noonsees" was selected because the
|
|
# individual word values ("noon" and "sees") are palindromes, thus making
|
|
# this test byte-order agnostic. If grep finds the string "noonsees" in
|
|
# the object file, the target platform stores float words in big-endian
|
|
# order. If grep finds "seesnoon", float words are in little-endian order.
|
|
# If neither value is found, the user is instructed to specify the
|
|
# ordering.
|
|
#
|
|
# Early versions of this macro (i.e., before serial 12) would not work
|
|
# when interprocedural optimization (via link-time optimization) was
|
|
# enabled. This would happen when, say, the GCC/clang "-flto" flag, or the
|
|
# ICC "-ipo" flag was used, for example. The problem was that under
|
|
# these conditions, the compiler did not allocate for and write the special
|
|
# float value in the data segment of the object file, since doing so might
|
|
# not prove optimal once more context was available. Thus, the special value
|
|
# (in platform-dependent binary form) could not be found in the object file,
|
|
# and the macro would fail.
|
|
#
|
|
# The solution to the above problem was to:
|
|
#
|
|
# 1) Compile and link a whole test program rather than just compile an
|
|
# object file. This ensures that we reach the point where even an
|
|
# interprocedural optimizing compiler writes values to the data segment.
|
|
#
|
|
# 2) Add code that requires the compiler to write the special value to
|
|
# the data segment, as opposed to "optimizing away" the variable's
|
|
# allocation. This could be done via compiler keywords or options, but
|
|
# it's tricky to make this work for all versions of all compilers with
|
|
# all optimization settings. The chosen solution was to make the exit
|
|
# code of the test program depend on the storing of the special value
|
|
# in memory (in the data segment). Because the exit code can be
|
|
# verified, any compiler that aspires to be correct will produce a
|
|
# program binary that contains the value, which the macro can then find.
|
|
#
|
|
# How does the exit code depend on the special value residing in memory?
|
|
# Memory, unlike variables and registers, can be addressed indirectly at run
|
|
# time. The exit code of this test program is a result of indirectly reading
|
|
# and writing to the memory region where the special value is supposed to
|
|
# reside. The actual memory addresses used and the values to be written are
|
|
# derived from the the program input ("argv") and are therefore not known at
|
|
# compile or link time. The compiler has no choice but to defer the
|
|
# computation to run time, and to prepare by allocating and populating the
|
|
# data segment with the special value. For further details, refer to the
|
|
# source code of the test program.
|
|
#
|
|
# Note that the test program is never meant to be run. It only exists to host
|
|
# a double float value in a given platform's binary format. Thus, error
|
|
# handling is not included.

#

# AX_CHECK_COMPILE_FLAG(FLAG, [ACTION-SUCCESS], [ACTION-FAILURE], [EXTRA-FLAGS], [INPUT])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Check whether the given FLAG works with the current language's compiler
|
|
# or gives an error. (Warnings, however, are ignored)
|
|
#
|
|
# ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on
|
|
# success/failure.
|
|
#
|
|
# If EXTRA-FLAGS is defined, it is added to the current language's default
|
|
# flags (e.g. CFLAGS) when the check is done. The check is thus made with
|
|
# the flags: "CFLAGS EXTRA-FLAGS FLAG". This can for example be used to
|
|
# force the compiler to issue an error when a bad flag is given.
|
|
#
|
|
# INPUT gives an alternative input source to AC_COMPILE_IFELSE.
|
|
#
|
|
# NOTE: Implementation based on AX_CFLAGS_GCC_OPTION. Please keep this
|
|
# macro in sync with AX_CHECK_{PREPROC,LINK}_FLAG.

#
|
|
# Look for OpenSSL in a number of default spots, or in a user-selected

#
|
|
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
|
|
#
|
|
# This macro sets OPENSSL_INCLUDES such that source files should use the

# openssl/ directory in include directives:
