It was assumed that elimination in LRA does not generate new reload insns. In the testcase the elimination of SFP subreg generates reload insn of the subreg and this insn is added at end of RTL code. The insn is also skipped for necessary processing. This results in ICE. The patch checks creation of reloads insn during elimination, insert them in the right place, and add them for later processing. gcc/ChangeLog: PR rtl-optimization/124572 * lra-eliminations.cc (lra_eliminate): Push new reload insns for eliminations in insns. gcc/testsuite/ChangeLog: PR rtl-optimization/124572 * gcc.target/aarch64/pr124572.c: New.

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*.
