2023-11-16Imposed limitations on supported instruction encodings.David Boddie
2023-11-16Build the Thumb suite by default.David Boddie
Create a library directory for Thumb-native Inferno.
2023-11-16Moved division and modulo operator support into the compiler.David Boddie
Fixed constant encoding in case 61.
2023-11-16Added support for AND instruction variants.David Boddie
2023-11-16Tidied up the thumbopfp function and added a case for ACMPD.David Boddie
2023-11-16Brought the order of operations in line with the VFP instructions in 5l for ↵David Boddie
easier comparison. Fixed encoding of MOVD and related operations so that their execution causes a trap to occur.
2023-11-16Added support for more floating point operations.David Boddie
Fixed bit flipping for a MOVD instruction.
2023-11-16Added entries to the optab for combinations that occur when compiling bits ↵David Boddie
of a kernel. Split ACMPF handling like the VFP support does in 5l.
2023-11-16Started trying to add missing instructions.David Boddie
2023-11-16Changed an entry in the opcode table to reflect the direction of conversion.David Boddie
Added references to instruction information.
2023-11-16Handled loads and stores using different base registers with slightly ↵David Boddie
different instructions.
2023-11-16Speculatively enable more FP instructions.David Boddie
2023-11-16Worked on converting ARM instructions to Thumb instructions for floating ↵David Boddie
point handling.
2023-11-16Removed unused array entry.David Boddie
2023-11-16Renumbered FP opcodes and imported cases from the arm.c assembler.David Boddie
Added a layer of indirection to float constants to encode them correctly in Thumb instructions.
2023-11-16Prevented change to regular ARM mode.David Boddie
2023-11-16Added FP instructions from the optab.c file.David Boddie

Fixes for spim architecture running on a Linux host Approved-by: Charles Forsyth
2021-02-03Merged in bugfix/parseman-space-escapes (pull request #12)Valery Ushakov
lib/parseman: recognize all troff space escapes Approved-by: Charles Forsyth
2021-01-05lib/parseman: recognize all troff space escapesValery Ushakov
parsetext() recognizes escapes for \& zero-width space, and \| narrow space (1/6 em-space in troff). Recognize also \^ - half-narrow space (1/12 em) and ignore it (found e.g. in dd(1)), and \0 - digit-width space and map it to plain space character (found e.g. in text(9)).
2021-01-04NetBSD/arm: segflush - use mprotect to add PROT_EXECValery Ushakov
ARM has separate read and execute protection bits so after writing out JIT code we need to make it executable.
2021-01-04NetBSD/arm: disable pax mprotect restrictions for emuValery Ushakov
ARM has separate read and execute protection bits so after writing out JIT code we need to make it executable with mprotect(2), but PAX wouldn't let us by default. Mark the emu binary so that this restriction is lifted. On other machines where this is not an issue set PAXCTL to a no-op.

2020-12-29NetBSD/asm-arm.S: use .L for local labels.Valery Ushakov
2020-12-29NetBSD/arm: initial supportValery Ushakov
This is more or less mechanical merge of existing NetBSD code and ARM-specific bits from Linux/arm files.
