2022-04-20Link -lgcc if it existsLucheng Zhang1-1/+2
2022-02-08Fix local variable register usage for ra (#268)Fangrui Song1-1/+1
See https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html#Local-Register-Variables "Other than when invoking the Extended asm, the contents of the specified register are not guaranteed." Also revert 90191ad93eac47d61ab9cc89084050ad1541d160.
2022-02-07Eliminate Wuninitialized for Clang/LLVM (#266)Zenithal1-1/+1
2020-02-02Support manually zeroing out BSS when booting (#188)James Clarke1-0/+5
Some ELF loaders, in particular gdb's load command for dynamically loading files into memory, which is often used to load binaries onto FPGAs over JTAG, do not zero out BSS, leaving the memory in whatever state it was previously in. Thus, introduce a new --enable-zero-bss configure flag, which will include code to zero out BSS when booting.
2019-12-09Added --with-abi configure option (#183)Nick Knight1-0/+3
* Added --with-abi configure option * Revised to preserve original semantics when user specifies --with-arch but not --with-abi or when the user specifies --with-arch but not --host.
2019-08-14Mark PK as version 1.0.0v1.0.0Palmer Dabbelt1-1/+1
Why not? Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>
2019-06-11configure: Add option to set physical memory start addressGabriel L. Somlo1-0/+7
For systems where physical memory is mapped to a start address different from 0x80000000, allow the default to be overridden using the --with-mem-start argument to the configure script. Signed-off-by: Gabriel Somlo <gsomlo@gmail.com>
2019-04-14configure.ac: use = instead of == to check for equality (#157)maxice81-1/+1
== is not specified by POSIX and will fail if a POSIX shell is called which is done by the configure script. Related to: https://github.com/void-linux/void-packages/issues/10949
2019-01-15Revert "Don't require a RISC-V libc and crt when configuring (#132)" (#140)Andrew Waterman1-1/+0
This reverts commit a02257a861a4d13f31868a27c197cfc5576101e1.
2019-01-04Don't require a RISC-V libc and crt when configuring (#132)James Clarke1-0/+1
2018-07-09Properly license all nontrivial filesAndrew Waterman1-0/+2
2018-06-21Replace the --enable-32bit option by --with-archZong Li1-23/+7
Get rid of the --enable-32bit option and switch to use --with-arch, which is more standard because it matches the GCC build. If --with-arch is not specified, it defaults to whatever the compiler's default is. The --with-abi is not necessary for this project. Unconditionally compile it with a no-float ABI.
2018-03-21Fix build with compilers defaulting to PIE (#90)aurel321-1/+1
Debian toolchain defaults to PIE, and I guess that will also be the case of most distributions. This cause bbl to be non-functional. This patch fixes that by adding -fno-PIE in the default CFLAGS.
2018-03-16Changed install_subdir to $host_alias with substituted 64->32 instead… (#89)Rishi Khan1-2/+2
* Changed install_subdir to $host_alias with substituted 64->32 instead of hardcoded riscv[32|64]-unknown-elf * Updated readme to reflect changes in install_subdir.
2018-03-15Don't link build-id stringAndrew Waterman1-0/+2
Closes #88
2017-11-03Remove the platform interfacePalmer Dabbelt1-7/+1
We now automatically detect everything that the platform interface used to be used for, so it's now obsolete!
2017-08-03Add the '--enable-print-device-tree' argumentPalmer Dabbelt1-0/+5
I'm trying to debug some device tree problems while booting Linux and figured it would be really nice to have access to the device tree while trying to debug these problems. I think this might be useful for lots of people, so I went ahead and cleaned up the code enough that it should actaully work in most cases.
2017-08-02Add the '--with-platform' argument and the sifive-vc707-devkit platformPalmer Dabbelt1-0/+6
Since we don't have a coherent platform specification right now, we've ended up with slightly different platforms between spike and our FPGA dev kit. For now I've added an autoconf option that allows users to select the relevant platform.
2017-08-02Add a platform interfacePalmer Dabbelt1-1/+1
SiFive's pk fork is the second one I've had to maintain, and it's a huge pain because people keep just leaving changes all over the tree. I want to introduce an interface that the platform-specific details can live behind so I don't have to keep doing these painful merges.

2016-07-16Support 32bit build (#27)Prashanth Mundkur1-3/+32
* Support configuration for a 32-bit build. * Regenerate configure.

Yuck.

2014-10-26Don't rely on the C libraryAndrew Waterman1-1/+0
2014-09-11Don't assume null pointers can't be dereferencedAndrew Waterman1-1/+1
This option breaks vm_init's access to word 0 to obtain the memory capacity.

2013-01-25rename binary to pk; change argv handlingAndrew Waterman1-1/+1
the new fesvr approach makes argv[0] = pk, rather than user program's name
2012-09-07Added rough emulation support for div/rem/mul.Christopher Celio1-1/+1

2011-03-24[pk] 32bit kernel + FPU emulation now compilesAndrew Waterman1-0/+1
2010-11-21[opcodes, pk, sim, xcc] made jumps shorter and PC-relativeAndrew Waterman1-1/+1
2010-10-15[pk, sim] added FPU emulation support to proxy kernelAndrew Waterman1-1/+1
2010-08-18[pk,fesvr] improved proxykernel build systemAndrew Waterman1-0/+102
Now uses a modified MCPPBS. Add --host=riscv to configure path. Front-end server now just searches PATH for riscv-pk, so just install the pk to somewhere in your path.
