a code and temp generator for the architectural target instead of for LLVM
* write the code for pure assembler routines using a GNU-style external
assembler writer for the target, with a decorator to wrap it in
LLVM module-level assembly statements
git-svn-id: trunk@31633 -
assembler writer that is compatible with the current architecture,
for use by the LLVM assembler writer to write inline assembly
git-svn-id: trunk@31631 -
that we can use assembler writers with different conventions from the
currently set target_asm (e.g. an x86 assembler writer for inline assembly
in LLVM IR)
git-svn-id: trunk@31628 -
case the section options contain the new option 'oso_sparse_data') in the
internal object writer (needed for the huge memory model)
git-svn-id: trunk@31503 -
last encountered section at the object cut location when writing a smartlinked
library with the internal assembler. This fixes the $HUGECODE directive with
the internal assembler on i8086 and maybe other things on other platforms,
that use library based smartlinking in combination with the internal asm.
git-svn-id: trunk@30615 -
TAArch64AppleAssembler to determine whether we have to add extra
parameters to support assembling via a pipe ("as" is a symlink to
clang for Arch64 on OS X, and needs to be explicitly told its going to
receive assembler code from standard input)
git-svn-id: trunk@29952 -
Precisize rules for selection of thumb instructions.
Add short-cut notation support for most simple Thumb2 instructions ( add r1,#4 instead of add r1,r1,#4 ).
git-svn-id: branches/laksen/armiw@29343 -
typed constant data
o llvm declarations now get an extra "initdata" list that contains the
typed constant data associated with this declaration (if any)
git-svn-id: branches/hlcgllvm@28111 -
to free up space for more ait_* types in taitype (can't have
more than 32 because they have to fit in a small set)
o factored out writing of floating point numbers as an array of
byte in the external assemblers
git-svn-id: branches/hlcgllvm@28105 -
* Change MIPS jump tables in PIC mode to use gp-relative constants, making them ABI-compliant and not requiring dynamic relocations.
git-svn-id: trunk@26886 -
check of "if not have_first_symbol and dosub then" always evaluate to
false (found by looking at the results of constant propagation :)
git-svn-id: trunk@26011 -
Therefor the cpu type (-Cp...) "coldfire" was split up into "isaa", "isaa+", "isab" and "isac". The Linux RTL can currently compiled for "68020", "isab" and "isac". For the other three Bcc.L must be handled differently (only Bcc.B/W supported) and for "68000" also EXT.L needs to be handled differently.
fpcdefs.inc:
+ define CPUCAPABILITIES if capabilities can be set for a certain CPU type (currently ARM, AVR and M68k)
options.pas:
* check for CPUCAPABILITIES instead of specific CPUs
assemble.pas:
- the handling of the CPU type is already done in m68k/ag68kgas.pas, Tm68kGNUAssembler.MakeCmdLine (and thereby already using the gascputypestr array!)
m68k/cpuinfo.pas:
- tcputype: remove "cpu_coldfire"
+ tcputype: add "cpu_isa_a", "cpu_isa_a_p", "cpu_isa_b" and "cpu_isa_c"
+ add "cpu_coldfire" constant which contains all Coldfire specific cpu types
* adjust "cputypestr" and "gascputypestr"
+ add tcpuflags and cpu_capabilities (DBRA restriction was checked with CPUCOLDFIRE, CAS/TAS will be needed for atomic operations and BRAL restriction was discovered during testing of new cpu types)
m68k/cgcpu.pas:
* adjust checks for "cpu_coldfire"
m68k/n68kadd.pas:
* don't use a BRA.L if it is not supported, but (at least for now) a BRA.W
aggas.pas:
* adjusted check for Coldfire
git-svn-id: trunk@25457 -
assemble.pas, TExternalAssembler.WriteSourceLine:
* don't generate an internal error if no module is found; if the system unit is compiled with -al there can be cases when fileinfo contains only zeros (though I wonder where this comes from; I'll need to investigate this when I have time)
git-svn-id: trunk@23631 -
assemble.pas, TExternalAssembler.WriteSourceLine:
* also respect a module change which can happen if the generated assembler code belongs to a specialized generic
