1.2.0 release notes |
|
|
|
|
|
|
|
new features: |
|
|
|
- time_t is now 64-bit on all archs (not just 64-bit archs) |
|
|
|
- character type & case mapping data updated to Unicode 12.1.0 |
|
|
|
- header-level support for new linux features in 5.3 and 5.4 |
|
|
|
|
|
|
|
performance: |
|
|
|
- new O(1) wchar_t case mapping implementation |
|
|
|
- i386 now uses C math code for exp, faster than old asm |
|
|
|
- mips math asm |
|
|
|
|
|
|
|
compatibility & conformance: |
|
|
|
- endian.h now aims to conform to future POSIX definition |
|
|
|
- support older compilers that don't accept powerpc math asm constraints |
|
|
|
- fdpic code in ldso was incompatible with valid optimizations in gcc 9+ |
|
|
|
- RLIMIT_RTTIME was missing from sys/resource.h |
|
|
|
|
|
|
|
bugs fixed: |
|
|
|
- wcwidth wrongly returned 0 for most of planes 4 and up |
|
|
|
- missing case mapping between U+03F3 and U+037F |
|
|
|
- wrong cacosh results for arguments with negative imaginary part |
|
|
|
- wrong catanf/catanl results for various classes of arguments |
|
|
|
- wrong return value for ungetc with argument outside [0,UCHAR_MAX] |
|
|
|
- posix_openpt with no ptys available produced wrong errno |
|
|
|
|
|
|
|
arch-specific bugs fixed: |
|
|
|
- sigcontext/regset definition mistakes & omissions on m68k, powerpc64 |
|
|
|
- fesetenv(FE_DFL_ENV) crashed on riscv64 |
|
|
|
- sh2 dynamic linker was broken since 1.1.21 (crash in stage 2b) |
|
|
|
- arm dynamic linker chose wrong tls/atomic variants since 1.1.21 |
|
|
|
- some math library functions returned excess precision on i386 |
|
|
|
- unconfirmed regression in fchmodat AT_SYMLINK_NOFOLLOW on mips* |
