2019-12-12csky: tidy csky_chars_to_numberAlan Modra1-4/+2
* csky-dis.c (csky_chars_to_number): Remove abort and unnecessary mask.
2019-12-11ubsan: csky: left shift cannot be represented in type 'int'Alan Modra1-4/+4
In the following buf is an unsigned char array, so elements are promoted to int before arithmetic operations. if (dis_info.info->endian == BFD_ENDIAN_BIG) while (n--) val |= buf[n] << (n*8); else for (i = 0; i < n; i++) val |= buf[i] << (i*8); * csky-dis.c (csky_chars_to_number): Rewrite. Avoid signed overflow when collecting bytes of a number.
2019-10-28Fix potentially illegal shift and assign operation in CSKY disassembler.Nick Clifton1-2/+2
* csky-dis.c (csky_chars_to_number): Check for a negative count. Use an unsigned integer to construct the return value.

2018-12-18Include bfd_stdint.h in bfd.hAlan Modra1-1/+1
This patch adds bfd_stdint.h to bfd.h, so that BFD can use size_t where appropriate in function parameters and return values. I also tidy a few other cases where headers are included twice. bfd/ * Makefile.am (bfdinclude_HEADERS): Add bfd_stdint.h. (BFD_H_DEPS): Add include/diagnostics.h.

2018-07-30Add support for the C_SKY series of processors.Andrew Jenner1-0/+1068
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc. This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about. bfd * Makefile.am (ALL_MACHINES, ALL_MACHINES_CFILES): Add C-SKY.
