* c-common.c (c_expand_expr_stmt): Apply default conversions to non-lvalue arrays if C99. * c-typeck.c (default_conversion): Split out code handling array-to-pointer and function-to-pointer conversions into a separate default_function_array_conversion function. (default_function_array_conversion): New function. Keep track of whether any NON_LVALUE_EXPRs were stripped. Return non-lvalue arrays unchanged outside C99 mode instead of giving an error for them. (build_component_ref): Use pedantic_non_lvalue when handling COMPOUND_EXPR. Don't handle COND_EXPR specially. (convert_arguments): Use default_function_array_conversion. (build_unary_op): For ADDR_EXPR, take a flag indicating whether non-lvalues are OK. (unary_complex_lvalue): Likewise. (internal_build_compound_expr): Use default_function_array_conversion. Apply default conversions to function in compound expression. (build_c_cast, build_modify_expr, digest_init, build_asm_stmt): Use default_function_array_conversion. * doc/extend.texi: Update documentation of subscripting non-lvalue arrays. Fixes PR c/461. testsuite: * gcc.dg/c90-array-lval-1.c, gcc.dg/c90-array-lval-2.c, gcc.dg/c99-array-lval-1.c, gcc.dg/c99-array-lval-2.c: Remove XFAILs. Adjust expected error texts. * gcc.c-torture/compile/20011106-1.c, gcc.c-torture/compile/20011106-2.c, gcc.dg/c90-array-lval-3.c, gcc.dg/c90-array-lval-4.c, gcc.dg/c90-array-lval-5.c, gcc.dg/c99-array-lval-3.c, gcc.dg/c99-array-lval-4.c, gcc.dg/c99-array-lval-5.c: New tests.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
