2023-08-17bpf: gas: consolidate handling of immediate overflowsJose E. Marchesi1-0/+23
This commit changes the BPF GAS port in order to handle immediate overflows the same way than the clang BPF assembler: - For an immediate field of N bits, any written number (positive or negative) whose two's complement encoding fit in N its is accepted. This means that -2 is the same than 0xffffffe. It is up to the instructions to decide how to interpret the encoded value. - Immediate fields in jump instructions are no longer relaxed. Relaxing to jump instructions with wider range is only performed when expressions are involved. - The manual is updated to document this, and testsuite adapted accordingly. Tested in x86_64-linux-gnu host, bpf-unknown-none target. gas/ChangeLog: 2023-08-17 Jose E. Marchesi <jose.marchesi@oracle.com> * config/tc-bpf.c (check_immediate_overflow): New function.

2023-07-30bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flagsJose E. Marchesi1-0/+5
This patch adds support for EF_BPF_CPUVER bits in the ELF machine-dependent header flags. These bits encode the BPF CPU version for which the object file has been compiled for. The BPF assembler is updated so it annotates the object files it generates with these bits. The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the appropriate ISA version if the user didn't specify an explicit ISA version in the command line. Note that a value of zero in EF_BPF_CPUVER is interpreted by the disassembler as "use the later supported version" (the BPF CPU versions start with v1.) The readelf utility is updated to pretty print EF_BPF_CPUVER when it prints out the ELF header: $ readelf -h a.out ELF Header: ...

2023-07-28bpf: gas: support relaxation of V4 jump instructionsJose E. Marchesi1-0/+36
The BPF jump-always instruction (JA), like all other jump instructions in the ISA, get a signed 16-bit displacement target argument denoted in number of 64-bit words minus one. This can sometimes be overflown. The BPF V4 ISA thus introduced support for a jump-always instruction (JAL) that gets a signed 32-bit displacement instead. This patch makes the BPF assembler to perform the following relaxations when the disp16 field gets overflown, unless the option -mno-relax is specified: JA disp16 -> JAL disp32 Jxx disp16 -> Jxx +1; JA +1; JAL disp32 Documentation and tests added.

2023-04-26gas: support for the BPF pseudo-c assembly syntaxGuillermo E. Martinez1-0/+32
This patch adds support to the GNU assembler for an alternative assembly syntax used in BPF. This syntax is C-like and very unconventional for an assembly language, but it is generated by clang/llvm and is also used in inline asm templates in kernel code, so we ought to support it. After this patch, the assembler is able to parse instructions in both supported syntax: the normal assembly-like syntax and the pseudo-C syntax. Instruction formats can be mixed in the source program: the assembler recognizes the right syntax to use. gas/ChangeLog: 2023-04-20 Guillermo E.
