We run Intel MCU psABI tests on Linux/ia32 with -miamcu. Since Intel MCU psABI has a different calling convention, the only Linux libc function allowed is "abort". asm-support.S contains some support functions as well as a subset of soft-fp, which is written in assembly with x87 instructions, to provide intrinsics needed by -miamcu so that Intel MCU psABI tests can run on Linux. * gcc.target/i386/iamcu/abi-iamcu.exp: New file. * gcc.target/i386/iamcu/args.h: Likewise. * gcc.target/i386/iamcu/asm-support.S: Likewise. * gcc.target/i386/iamcu/defines.h: Likewise. * gcc.target/i386/iamcu/macros.h: Likewise. * gcc.target/i386/iamcu/test_3_element_struct_and_unions.c: Likewise. * gcc.target/i386/iamcu/test_basic_64bit_returning.c: Likewise. * gcc.target/i386/iamcu/test_basic_alignment.c: Likewise. * gcc.target/i386/iamcu/test_basic_array_size_and_align.c: Likewise. * gcc.target/i386/iamcu/test_basic_returning.c: Likewise. * gcc.target/i386/iamcu/test_basic_sizes.c: Likewise. * gcc.target/i386/iamcu/test_basic_struct_size_and_align.c: Likewise. * gcc.target/i386/iamcu/test_basic_union_size_and_align.c: Likewise. * gcc.target/i386/iamcu/test_bitfields.c: Likewise. * gcc.target/i386/iamcu/test_complex_returning.c: Likewise. * gcc.target/i386/iamcu/test_passing_floats.c: Likewise. * gcc.target/i386/iamcu/test_passing_integers.c: Likewise. * gcc.target/i386/iamcu/test_passing_structs.c: Likewise. * gcc.target/i386/iamcu/test_passing_structs_and_unions.c: Likewise. * gcc.target/i386/iamcu/test_passing_unions.c: Likewise. * gcc.target/i386/iamcu/test_struct_returning.c: Likewise. * gcc.target/i386/iamcu/test_varargs.c: Likewise.

2015-06-29Wunused-parameter warnings are given from cgraph::finalize_function,Manuel López-Ibáñez15-22/+78
which is the middle-end. This is an oddity compared to other -Wunused-* warnings. Moreover, Fortran has its own definition of -Wunused-parameter that conflicts with the middle-end definition. This patch moves the middle-end part of Wunused-parameter to the C/C++ FEs. I'm not sure if other FEs expected this warning to work. If so, they do not seem to test for it.
