Replace config-time define HOST_WORDS_BIGENDIAN

2022-04-06T08:50:37+00:00

Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

meson: linux-user

2020-08-21T10:30:38+00:00

The most interesting or most complicated part here is the syscall_nr.h generators. In order to keep the generation logic all in meson.build, I am adding to config_target the name of the .tbl file, and making the generated file syscall_nr.h for input file syscall.tbl. For architectures where the input file is not named syscall_nr.tbl, syscall_nr.h has to be a source file; it's just a forwarder for x86 (i386/x86_64), while for MIPS64 it chooses between N32 and N64 ABIs.

linux-user/arm/nwfpe: Check coprocessor number for FPA emulation

2018-01-11T13:25:39+00:00

Our copy of the nwfpe code for emulating of the old FPA11 floating point unit doesn't check the coprocessor number in the instruction when it emulates it. This means that we might treat some instructions which should really UNDEF as being FPA11 instructions by accident. The kernel's copy of the nwfpe code doesn't make this error; I suspect the bug was noticed and fixed as part of the process of mainlining the nwfpe code more than a decade ago. Add a check that the coprocessor number (which is always in bits [11:8] of the instruction) is either 1 or 2, which is where the FPA11 lives.
