Bug 2213 – unrecognizable insn are generated when cross-compiling

Hi, When applying latest trunk to cegcc with mingw32ce configuration project I get some issues but I think that more generally this report could help people to cross-compile D on different architectures. Main issues are related to unrecognizable instruction due to some windows functions. Another issue is about x86 assembly used in some modules. 1) in libphobos/std/c/windows/com.d It seems that Windows InterlockedIncrement function generates bad instruction make[3]: Entering directory `/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/arm-mingw32ce/libphobos' true "AR_FLAGS=rc" "CC_FOR_BUILD=gcc" "CC_FOR_TARGET=/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/xgcc -B/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/ -B/opt/mingw32ce/arm-mingw32ce/bin/ -B/opt/mingw32ce/arm-mingw32ce/lib/ -isystem /opt/mingw32ce/arm-mingw32ce/include -isystem /opt/mingw32ce/arm-mingw32ce/sys-include" "CFLAGS=-O2 -g -O2 " "CXXFLAGS=-g -O2 " "CFLAGS_FOR_BUILD=-g -O2" "CFLAGS_FOR_TARGET=-O2 -g -O2 " "INSTALL=/usr/bin/install -c" "INSTALL_DATA=/usr/bin/install -c -m 644" "INSTALL_PROGRAM=/usr/bin/install -c" "INSTALL_SCRIPT=/usr/bin/install -c" "LDFLAGS=" "LIBCFLAGS=-O2 -g -O2 " "LIBCFLAGS_FOR_TARGET=-O2 -g -O2 " "MAKE=make" "MAKEINFO=makeinfo --split-size=5000000 --split-size=5000000 " "PICFLAG=" "PICFLAG_FOR_TARGET=" "SHELL=/bin/sh" "RUNTESTFLAGS=" "exec_prefix=/opt/mingw32ce" "infodir=/opt/mingw32ce/info" "libdir=/opt/mingw32ce/lib" "includedir=/opt/mingw32ce/include" "prefix=/opt/mingw32ce" "tooldir=/opt/mingw32ce/arm-mingw32ce" "gdc_include_dir=/opt/mingw32ce/include/d2/4.1.0" "AR=arm-mingw32ce-ar" "AS=/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/as" "LD=/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/collect-ld" "RANLIB=arm-mingw32ce-ranlib" "NM=/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/nm" "NM_FOR_BUILD=" "NM_FOR_TARGET=arm-mingw32ce-nm" "DESTDIR=" "WERROR=" DO=all multi-do # make /d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/gdc -B/d/Professionnel/Projets/cegcc/src/build-mingw32ce/gcc/./gcc/ -B/opt/mingw32ce/arm-mingw32ce/bin/ -B/opt/mingw32ce/arm-mingw32ce/lib/ -isystem /opt/mingw32ce/arm-mingw32ce/include -isystem /opt/mingw32ce/arm-mingw32ce/sys-include -o std/c/windows/com.o -g -frelease -O2 -nostdinc -pipe \ -I /d/Professionnel/Projets/cegcc/src/gcc/libphobos -I /d/Professionnel/Projets/cegcc/src/gcc/libphobos/internal/gc -I ./arm-mingw32ce -c /d/Professionnel/Projets/cegcc/src/gcc/libphobos/std/c/windows/com.d /d/Professionnel/Projets/cegcc/src/gcc/libphobos/std/c/windows/com.d: In member function 'AddRef': /d/Professionnel/Projets/cegcc/src/gcc/libphobos/std/c/windows/com.d:224: error: unrecognizable insn: (call_insn/j 13 12 14 0 /d/Professionnel/Projets/cegcc/src/gcc/libphobos/std/c/windows/com.d:223 (parallel [ (set (reg:SI 0 r0) (call (mem:SI (reg/f:SI 105) [0 S4 A32]) (const_int 0 [0x0]))) (return) (use (const_int 0 [0x0])) ]) -1 (nil) (nil) (expr_list:REG_DEP_TRUE (use (reg:SI 0 r0)) (nil))) /d/Professionnel/Projets/cegcc/src/gcc/libphobos/std/c/windows/com.d:224: internal compiler error: in extract_insn, at recog.c:2084 Please submit a full bug report, with preprocessed source if appropriate.

compiled with gcc 4.1.0. All the bad insn error seems to be fixed when passing -fno-optimize-sibling-calls.

Closing as we no longer support this version of GCC. MinGW binaries are available for version 4.5 I believe and I haven't had such report that this issue is occurring.
