jiang 089dea355a tcc on i386 are still having problems at work.Thank Roy report again. Struck on several variables can be connected to commit in the register. I am worried whether tcc can run the os. Since my machine is ubuntu 64 bits I can test my machine. 2014-05-03 23:51:09 +08:00

jiang e647c3137d Fix x86-64 vla 
For example, it should look like this
High stack
-------------
----- Func_ret_sub
------------
---- Vla stack
-------------
---- Known loc
--------------
Low

Increased loc_stack () function is used for temporary stack management, call save_reg (), released by load ()
Like this
Before use
High
----- Known loc
----
---
----
---- Pop_stack
Low
loc_stack (size, 1)
After use
High
----- Known loc
---- Pop_stack
---
----
----
Low

jiang 5b52a44b52 gen_putz () and struct_copy (), is to reduce the third-party call that 
generates faster code tcc
Now only for x86-64
parse_number also to reduce the reliance on third-party libraries, allowing
faster analysis tcc

grischka 504d40a328 Attention: never use hard tabs other than 8 (eight) wide 
The attached fix (libcrt.c) is just one example.  There seem
many more such introduced from latest commits that look badly
formatted in anyone else's editors and should be fixed.

General recommended policy:
- if possible, do not add new hard tabs ('\t') at all.
  Use spaces (soft tabs) instead
- in any case, configure your editor to read/write hard tabs
  with width of 8 (eight)

Also:
- Avoid merge commits (unless for very good reason).  Instead
  use "git cherry-pick" or "git rebase" to put your commits on
  top of the public branch.  ref: 2a8905c93b

Also:
- jiang: please explain what you are doing, in the commit message
  and on the list. Subscribe to the mailing list to receive feedback
  from people for your work.

  For example, what was wrong with 'parse_number'? Show a test
  case and how your version fixes it (it is slower btw).

grischka 2ac238fc50 tccpe: adjust for new 'hidden' symbols feature 
in order to avoid conflicts with windows specific (ab)usage

Thomas Preud'homme 6b7a6fcbc8 Improve efficiency of macro concatenation 
As per grischka comment, always output a space after macro concatenation
instead of trying to detect if it's necessary as the current approach
has a huge cost.

Michael Matz e69c506617 x86_64: Handle PLT relocs to hidden symbols 
For calls to hidden symbols we don't need a PLT slot, rewrite
the reloc into PC32.

Michael Matz a9fda392a0 Parse assembler .hidden directive 
This makes TCCs assembler understand the '.hidden symbol' directive
(and emits a STV_HIDDEN ELF symbol then).

Michael Matz fbda78aefe Parse and emit hidden visibility 
This adds parsing of (GCC compatible) visibility attribute
in order to mark selected global symbols as hidden.  The generated
.o files contain hidden symbols already, the TCC linker doesn't
yet do the right thing.

minux 9714d2e75f build: add initial NetBSD support. 
Not able to generate ELF files on NetBSD yet (lacks the note and crt1.o
is actually named crt0.o on NetBSD), but -run works with these extra
defines:
-D__lint__ -D"__symbolrename(x)=asm(#x)" -D__NetBSD__

The -D__lint__ is an ugly hack, TCC should be able to emulate GCC just
fine, but it seems TCC doesn't support __builtin_va_list yet?
	typedef __builtin_va_list __va_list;
/usr/include/sys/ansi.h:72: error: ';' expected (got "__va_list")

grischka f90bad0925 tests2: cleanup 
- remove -norunsrc switch
  Meaning and usage (-run -norun...???) look sort of screwed.  Also
  general usefulness is unclear, so it was actually to support exactly
  one (not even very interesting) test
